• Do not connect brake resistor directly between DC bus (+) (-) terminals, otherwise fire may occur!
• Encoder shall use shielded wire single and ensure reliable earthing for terminal of shielding layer!

1.1.4 Before electrifying:

Caution

• Please confirm the consistence between voltage class of input power and rated voltage class of frequency convertor; correctness of wiring positions of power input terminal (R, S, T) and output terminals (U, V, W). Check if any short circuit of peripheral circuit connecting to driver and if wiring circuit is tightened, otherwise driver may be damaged!
  ● Neither part of frequency convertor needs withstand voltage test as the product has been tested!

Danger

Electrify frequency convertor after covering cover plate, otherwise electric shock may occur!
- Wiring of all periphery accessories shall comply with manual guidance and keep correct wiring as per circuit connection method in manual, otherwise accident may occur!

1.1.5 After electrifying:

1.2 Precautions

1.2.1 Insulation inspection of motor

When firstly using motor, using motor again after putting for a long time and regularly checking motor, insulation inspection of motor is essential to prevent damaging frequency convertor due to invalid insulation of motor winding. During insulation inspection, separate motor wire from frequency convertor. 500V voltage-type tramegger is suggested and ensure measured insulation resistance≥5MΩ.

1.2.2 Thermal protection of motor

If selected motor does not match with rated capacity of frequency convertor, especially if rated power is larger than that of frequency convertor, please adjust related parameter values of motor protection or install thermal relay in front of motor for protection.

1.2.3 Operation above power frequency

The frequency convertor offers output frequency at 0Hz\~3200Hz. If users need to operate at above 50Hz, please consider the tolerance of mechanical device.

1.2.4 Vibration of mechanical device

Mechanical resonance point of load device may exist at certain output frequency of frequency convertor, and hopping frequency parameter can be set to avoid.

1.2.5 About heating and noise of motor

Output voltage of frequency convertor is PWM wave containing certain harmonic, so temperature rise, noise and vibration of motor will slightly increase when comparing with power frequency operation.

1.2.6 Voltage-sensitive parts or capacitance of improving power factor exist on output side

Output of frequency convertor is PMB wave. If capacitance of improving power factor or voltage dependent resistor for thunder prevention is installed on output side, instantaneous over current and even damage of frequency convertor can be caused easily. Please do not use.

1.2.7 Switching devices such as contactor for input and output terminals of frequency convertor

If contactor is installed between power and input terminal of frequency convertor, this contactor is not allowed to control the start and stop of frequency convertor. If this contactor is required to control the start and stop of frequency convertor, the interval should be not less than one hour. Frequent charging and discharging will easily reduce the lifespan of capacitor within frequency convertor. If switching devices such as contactor are installed between output terminal and motor, ensure the operation of frequency convertor without output, otherwise module damage may occur easily.

1.2.8 Use beyond rated voltage value

It's not suitable to use this series frequency convertor beyond operating voltage range allowed by the manual, otherwise device damage may be caused. If necessary, please use corresponding voltage boosting or dropping equipment for voltage transformation.

1.2.9 Three-phase input changes to be two-phase input

Do not change three-phase frequency convertor to be two-phase, otherwise fault or damage may occur.

1.2.10 Lightening impulse protection

There's lightening stroke over-current protection device in frequency convertor, so it has certain self-protection ability for inductive thunder. If lightening stroke is frequent in the place of client, additional protection in front of frequency convertor is essential.

1.2.11 Altitude and derating use

In the region with altitude exceeding 1,000m, the heat dissipation effect of frequency convertor weakens due to thin air, so it's necessary to derate for use. Please contact our company for consultation.

1.2.12 About adaptive motor

1) Standard adaptive motor is four-pole squirrel-cage asynchronous induction motor. If it's not above motor, please select frequency convertor as per rated current of motor.
2) Cooling fan and rotor spindle of non-variable frequency motor is coaxial connection. If rotation speed reduces, cooling effect of fan will reduce, so the occasion of overheating motor should be installed with strong exhaust fan or changed to be variable frequency motor.
3) Standard parameters of adaptive motor have been built in frequency convertor. It's necessary to identify motor parameters or modify default value based on actual situation to conform to actual value as far as possible, otherwise operation effect and protection performance may be affected.
4) Short circuit of cable or within motor can lead to alarm and even explosion of frequency convertor. Please firstly conduct insulation short-circuit test for initially installed motor and cable, and it's also essential for daily maintenance. Please completely separate frequency convertor from tested part when conducting the test.

2.7 Routine maintenance of frequency convertor

2.7.1 Routine maintenance

The influence of environment temperature, humidity, dust and vibration will lead to aging of internal components and potential fault, or reduce lifespan of frequency convertor, so it's necessary to conduct routine and regular maintenance.

Routine inspection items:

1) If any abnormal change of sound during motor operation
2) If any vibration during motor operation
3) If any change of installing environment for frequency convertor
4) If normal work of cooling fan for frequency convertor
5) If overheating of frequency convertor

2.7.2 Regular inspection

Regular inspection items:

1) Inspect air channel and clean regularly
2) Inspect if any loosening of screw
3) Inspect if any arc trace of wiring terminal

2.7.3 Storage of frequency convertor

After purchasing frequency convertor, users should pay attention to temporary and long-term storage:

1. Put in packaging box of our company as per original package for storage.
2. Long-term storage will lead to deterioration of electrolytic capacitor. Ensure electrifying once for at

least 5 hours within 2 years, and voltage regulator should be used to gradually increase input voltage to rated value.

2.8 Warranty

Free maintenance only suit to frequency convertor. If any fault or damage under normal use, our company is liable for maintenance for 18 months (since the date of leaving factory and barcode on machine prevails). If beyond 18 months, rational maintenance fee will be charged. Under below conditions, certain maintenance fee will be charged within 18 months: device damage caused by violating stipulations in manual; damage caused by fire, flood and abnormal voltage, etc; damage caused by using frequency convertor for abnormal functions. Related service fee will be calculated as per unified standard of manufacturer. If any contract, the contract will prevail.

2.9 Model selection guidance of braking parts

Figure 2-7 is guidance data. Users can select different resistance value and power based on actual situation (but resistance value should not be lower than recommended value in figure, the power can be large). The selection of braking resistance depends on motor power in actual application system, and it's related to system inertia, deceleration time, potential energy load, so uses can select based on actual situation. The larger the system inertia, the shorter the deceleration time and three frequency the braking will be, so braking resistance should select large power and little resistance value.

2.9.1 Selection of resistancevalue

During braking, regenerated energy of motor is almost fully consumed on braking resistance. Formula is below: U*U/R=Pb

U----braking voltage of stable braking (vary with different systems, generally 700V for 380VAC) Pb----braking power

2.9.2 Power selection of braking resistance

In theory, power of braking resistance conforms with braking power.

Derating to 70% can be used.

Formula: 0.7Pr=PbD

Pr----power of resistance; D----braking frequency (proportion in whole process during regeneration)

Uncoil/Coil ----20 \~30%

Centrifuge----50%\~60%

Casual braking load----5%

10% in general

1) Install frequency convertor vertically so that heat can dissipate upward, prohibit inverting. If there are multiple frequency converters in cabinet, abreast installation is suggested. For the occasions requiring top and bottom installation, install thermal insulation guide plate as per drawing 3-1.

2) Installation space follows by drawing 3-1 to ensure heat dissipation space of frequency convertor. Consider heat dissipation situation of other components within cabinet.
3) Installation bracket shall be flame retardant material.
4) For the occasion with metal dust, suggest installing radiator outside cabinet. The space of full sealing cabinet should be as large as possible.

3.1.3 Disassembly and installation of lower cover plate

Frequency convertor <18.5kW adopts plastic shell. The disassembly of lower cover plate of plastic shell refers to figure 3-2, 3-3. Push out hook of lower cover plate from inside with tool.

Figure 3-2 Disassembly drawing of lower cover plate of plastic shell

Figure 3-3 Disassembly drawing of lower cover plate of metal plate shell

Frequency convertor >18.5kW adopts metal plate shell. The disassembly of lower cover plate of metal plate shell refers to figure 3-3. Unscrew the screw on lower cover plate directly with tool.

Part name	Installing Functional	description
Air switch	Front of input circuit	Break power if any overcurrent of downstream equipment
Contactor	Input side of air switch and convertor	Turn on/off power of convertor. Avoid frequent on/off operation of convertor through contactor (< twice every minute) or starting operation directly
AC input reactor	Input side of convertor	Promote power factor on input side; eliminate higher harmonic on input side and prevent device damage caused by voltage waveform distortion; eliminate unbalanced input current caused by unbalance between power phase
EMC input filter	Input side of convertor	Reduce external conduction and radiated interference of convertor; reduce conduction interference from power end to convertor, promote antijamming capability of convertor
DC reactor	DC bus side of convertor	Promote power factor on input side; enhance efficiency and heat stability of convertor. Eliminate influence of higher harmonic on input side on convertor, reduce external conduction and radiated interference
AC output reactor	Between output side of convertor and motor. Install near frequency convertor	Output side of convertor contains much higher harmonic. If motor is far away from convertor, much distributed capacitance exists in circuit. Certain harmonic may produce resonance in circuit, which will damage insulating property of motor and even motor, produce large leak current and cause frequent protection of convertor. The distance between convertor and motor generall exceeds 50m, suggest installing output AC reactor

(+), (-)	Positive/negative terminals of DC bus	Input point of DC bus
(+), PB	Connection terminal of brake resistance	Connect brake resistance
U, V, W	Output terminal of convertor	Connect three-phase motor
PE ±	Earthing terminal	Earthing terminal

2) Description of terminal of main circuit for single-phase frequency convertor

Terminal marking	Name	Description
R、S、T	Input terminal of three-phase power	Connection point of AC input three-phase power
(+), (-)	Positive/negative terminals of DC bus	Input point of DC bus and brake unit
(+), PB	Connection terminal of brake resistance	Connect brake resistance
P1, (+)	Connection terminal of external DC reactor	Connection point of external DC reactor
U, V, W	Output terminal of convertor	Connect three-phase motor
PE	Earthing terminal	Earthing terminal

Wiring precautions:

a) Input power L1, L2 or R, S, T:
b) Wiring on input side of convertor has no requirement on phase sequence. Wiring precautions:

1: (+) (-) terminals of DC bus: there's residual voltage for DC bus (+) (-) immediately after outage. Contact after CHARGE light extinguishes and confirm it's <36V, otherwise there is risk of electric shock.
2: When selecting external braking component, avoid inverse connection of (+) (-) polarity, otherwise it will lead to damage of frequency convertor and even fire.
3: Wiring length of brake unit should not exceed 10m. Twisted pair or tight double-line should be used for parallel wiring. Do not connect brake resistance directly to DC bus, otherwise it will lead to damage of frequency convertor and even fire.

c) Connection terminal (+), PB of brake resistance:

Confirm the model of built-in brake unit, and connection terminal of brake resistance is valid.

Model selection of brake resistance refers to recommended value and wiring distance should be <5m, otherwise frequency convertor may be damaged.

d) Connection terminal P1, (+) of external DC reactor

For the frequency convertor at above 220V37KW and 380V75kW, connection strap between P1 and (+) terminals needs to be removed when installing DC reactor externally, and connect DC reactor between two terminals.

e) U, V, W on output side of frequency convertor: output side of frequency convertor shall not connect capacitor or surge absorber, otherwise it will lead to frequent protection and even damage of convertor. Due to influence of distributed capacitance, if motor cable is too long, electric resonance will produce easily, which will damage motor insulation or produce large leak current and frequent protection of convertor. If motor cable is >100m, AC input reactor should be installed.

f) Earthing terminal PE

For different models, the marking of earthing terminal may be different, but the meaning is same. In above descriptions, means that earthing marking is PE or .

Keep reliable earthing of earthing terminal and resistance value of ground wire should be <0.1 , otherwise it will lead to abnormal operation and even damage of device. Do not use earthing terminal PE or 12 and N terminal on null line of power in common.

4) Wiring description of control terminals

a) Analog input terminal:

Due to weak analog voltage signal, it's easily influenced by external interference, shield cable is commonly used and wiring distance is as short as possible, which should not exceed 20m as shown in Figure 3-7. In the occasion where certain analog signal is seriously interfered, the side of analog signal source should be installed with filter capacitor or ferrite core as shown in Figure 3-7.

4.2 Viewing and modifying methods of function code

Operation panel, frequency converter adopts three-level menu structure for parameter settings and other operations. Three-level menus are: function parameter group (first level)→function code (second level)→function code setting (second level). Operational flow is shown in Figure 4-2.

    style D fill:#fcc,stroke:#333

Figure 4-2 Flow chart of three-level menus

Instructions: when operating second-level menu, press the DATA key or ENTER key to return to the second-level menu. The difference is: press ENTER to save the setup parameter and return to the second-level menu, and then automatically shift to the next function code; press the SET key will directly return to the second-level menu without saving the parameters, and return to the current function code.

Example: the function code P3-02 is set to change from 10.00Hz

15.00Hz. (Bold text indicates the flashing bit)

graph TD
    A["50.00"] -->|DAT| B["P0"]

    G -->|DATA| H["P3"]
    H -->|DATA| I["P3-03"]
    I -->|ENTER| J["015.00"]

Under status of second-level menu, if there is no flashing bit for parameters, the function code can't be modified, and the possible reasons are below:

1) The function code is parameter that can't be modified, such as actual detection parameter and

operation record parameter, etc.

2) The function code can't be modified under running status, and it can only be modified afterhalting.

4.3 Parameter display mode

Parameter display mode is mainly set for users to view functional parameters with different spread patterns based on actual demand, and there are three parameter display modes.

User-defined parameter mode	User-defined functional parameters (define 32 parameters at most), users can confirm functional parameters to be displayed through PE group
User-modified parameter mode	Functional parameters being not consistent with factor default

Related functional parameters are PP-02 and PP-03 as below:

PP-02	Functional parameter mode display property		Factory default	11
	Setting range	Unit	U group display selection
		0	Not display
		1 Display
		Decade	A group display selection
		0	Not display
		1 Display
PP-03	Defined parameter mode display selection		Factory default	00
	Setting range	Unit	User-defined parameter display selection
		0 Not display
		1	Display
		Decade	User-modified parameter display selection
		0 Not display
		1	Display

If defined parameter mode display selection (PP-03) exists to be one display, different parameter display modes can be switched through QSM key.

Display code of each parameter display mode is as below:

Parameter display mode Display
Functional parameter mode	- bASE
User-defined parameter mode	-115Fr
User-modified parameter mode	-- [ --

Switching mode is as follows:

2: be suitable for variable torque load of designated rated parameters (load of fan and pump)

P0-01	Control mode of 1^st motor		Factory default	0
	Setting range	0	No speed Sensor vector control (SVC)
		1	Speed sensor vector control (FVC)
		2	V / F control

0: No speed Sensor vector control

The open-loop vector control is suitable for general high-performance control applications. One frequency convertor can only drive one motor such as load of machine tools, centrifuges, wire drawing machine, injection molding machine, etc.

1: Speed sensor vector control is a closed loop vector control. Motor-side must be installed with encoder. The frequency convertor must be mached with the same type of PG card with encoder. It is suitable for high-precision speed control or torque control applications. One inverter can only drive one motor such as load of paper-making machinery, cranes, elevators, etc.
2: V / F control is suitable for the ooccasion with less demand on load, or one frequency convertor drives multiple motors such as fans and pumps load. It can be used for one frequency convertor to drive multiple motors.

Prompt: motor parameter identification procedure is required when selecting vector control mode. Only accurate motor parameters can take advantage of the vector control mode. By adjusting the parameters of speed regulator in function code in P2 group (2 is second group), better performance can be achieved.

P0-15	Carrier frequency	Factory default	Related to machine type
	Setting range	0.5kHz~16.0kHz

This function adjusts the carrier frequency of the inverter. By adjusting the carrier frequency, it can reduce motor noise, avoid the resonance point of the mechanical system, and reduce interference and line-to-ground leakage current of the inverter.

When the carrier frequency is low, output current higher harmonic component increases, motor loss increases, and motor temperature increases. When the carrier frequency is high, motor loss decreases, motor temperature decreases, But the inverter loss increases, inverter temperature increases and interference increases.

Carrier frequency adjustment will affect the following properties:

Carrier frequency	Low → high
Motor noise	Large → small
Output current waveform	Bad → good
Temperature rise of motor	High → low
Temperature rise of convertor	Low → high
Leakage current	Small → large
External radiated interference	Small → large

For different power inverters, carrier frequency's factory settings are different. Although users can modify, but note: If the value of the carrier frequency is higher than the factory set, it will cause the

inverter heat sink temperature increase. In this case the user needs to derating for the inverter, or there is the danger of overheating inverter alarm.

P0-16	Carrier frequency adjusts with temperature	Factory default	0
	Setting range	0: no1: yes

Carrier frequency temperature adjustment means when the inverter detects its own heat sink temperature is high, it will automatically reduce the carrier frequency in order to reduce the temperature rise of the inverter. When the heat sink temperature is low, the carrier frequency is gradually restored to the set value. This feature can reduce the chance of inverter overheating alarm.

P1-06 \~ P1-10 is asynchronous motor parameters, these parameters generally do not have the motor nameplate, auto-tuning to get through the drive. Among them, “Induction Motor static tuning” can only get three parameters P1-06 \~ P1-08. But the “asynchronous motors complete tuning” can be obtained here except all five parameters, you can also get the encoder phase sequence, current loop PI parameters and others.

When changing motor rated power (P1-01) or the motor rated voltage (P1-02), the inverter will automatically modify the parameter value P1-06 \~ P1-10, and make these five parameters back to the usual standard Y series motor parameters.

Drive is running at different frequencies, you can select a different speed loop PI parameters. When operating frequency is smaller than the switching frequency 1 (P2-02), the speed loop PI adjustment parameters are P2-00 and P2-01. When the operating frequency is greater than the switching frequency 2, the speed loop PI adjustment parameters are P2-03 and P3-04. Speed loop PI parameters between switching frequency 1 and switching frequency 2 are the two group of PI parameters linear switching. Shown in Figure 6-2:

Figure 6-2 Diagram of PI parameters

Through setting the proportional coefficient of speed regulator and integration time, you can adjust vector control speed dynamic response characteristic.

Increasing the proportional gain, reducing the integration time can accelerate the dynamic response of the speed loop. However, the proportional gain is too large or the integral time too small may cause the system to vibrate. Recommend adjustment method:

If the factory parameters can not meet the requirements, then the value of the parameter in the factory on the basis of fine-tuning. Increase the proportional gain first to ensure that the system does not oscillate; then decrease the integration time, the system has quick response characteristics and small overshoot.

Note: As PI parameters are set incorrectly, it may cause large overshoot speed. Even when students fall overshoot overvoltage fault.

In vector control mode, the speed loop regulator output torque current command, the parameters for the torque command filter. This parameter is generally no need to adjust the speed fluctuations that may be appropriate to increase the filtering time; If the motor oscillation occurs, it should be appropriate to reduce this parameter.

Speed loop filter time constant is small, the output torque of the drive may be volatile, but the response speed is fast.

P2-08	Vector control over	Factory	64
	Setting range	0~200

During the deceleration, the over-excitation control bus voltage rise can be suppressed to avoid overvoltage fault. Greater the over excitation gains, stronger the suppression has effect.

For conditions that in the inverter deceleration process, it is easier to be over-pressured and sounds alarm, you need to improve the over excitation gain. But if excitation gain is too large, easily lead the output current to increase; you need to weigh in the application.

For the case of small inertia, deceleration of the motor voltage rise does not appear, it is recommended that the over excitation gain is 0; For braking resistance of the occasion, it is also suggested that over-excitation gain is set to 0.

Vector control current loop PI adjustment parameters. The complete tuning parameters in an asynchronous machine or synchronous machine will automatically load after tuning, generally do not need to modify.

What needs to be reminded is that the current loop integral controller, instead of using the integration time as a dimension, but directly set the integral gain. PI current loop gain is set too high, it may cause the entire control loop oscillation, so when current oscillations or torque ripple is large, it can be reduced manually for PI proportional gain or integral gain here.

P3 group-V/F control parameters

The function code only for V / F control is effective. For vector control, it is invalid.

V / F control is suitable for fans, pumps and other general load, or a inverter with multiple motors, or inverter power and motor power quite different applications.

		6	1.6 times V / F
		8	1.8 times V / F
		9	Retention

2: Multi-point V / F. Suitable for fans, pumps and other centrifugal load.

3\~8: VF curve between the straight line between the PF and VF square.

10: VF completely separate mode. Then the output frequency of the inverter output voltage independent of each other, the output frequency is determined by the frequency source. But output voltage is determined by P3-13 (VF isolated voltage source).

VF complete separation mode, Generally used in induction heating, power inverter, torque motor control and other applications.

11: VF semi-separation mode.

In this case V and F are proportional, but proportional to the voltage source by setting P3-13, and the relationship between V and F are also group P1 rated motor voltage related to the rated frequency.

Suppose the input voltage source is X (X is 0 to 100% of the value), the output voltage V F of the relationship between the inverter and the frequency is:

V / F=2*X* (Motor rated voltage) / (rated motor frequency)

As to compensate for V / F control low frequency torque characteristics, make increase compensation for the low-frequency inverter output voltage. However, the torque boost is set too large, the motor overheating, inverter over-current.

When the load is heavy and the motor starting torque is not enough, it is recommended to increase this parameter. Light can be reduced when the load torque boost. When the torque boost is set to 0.0, the inverter is automatic torque boost, torque boost at this time according to the drive motor stator resistance parameters calculated automatically required.

VF Slip compensation. It can be compensated induction motor generated when the load increases the motor speed deviation when the load changes the motor speed can be stable.

VF Slip compensation gain is set to 100.0%, indicating that slip when the motor with a rated load compensation to the motor rated slip. But the motor rated slip, the drive motor rated frequency group by P1 and rated speed to get own calculations.

Adjust VF rpm slip compensation gain, generally when the rated load, the motor speed and the target speed is substantially the same as the principle. When the motor speed and the target value is not the same, you need to be properly fine-tune the gain.

P3-10	VF over excitation gain	Factory default	6

Parameter description

Specification of high-performance vector convertor

The above function codes are generally used to bias the output amplitude and zero drift correction analog output. It can also be used to customize the desired output curve AO.

If zero offset by “b” represents the gain by k, the actual output by Y, X represents standard output, the actual output is: Y=kX+b . Wherein, AO1, AO2 zero-bias factor of 100% corresponds to 10V (or 20mA), it refers to the standard output in the absence of bias and gain correction, output 0V \~ 10V (or 0mA \~ 20mA) corresponding to the amount of the analog output.

For example: If the analog output is the operating frequency, at a frequency of 0 output 8V, frequency is the maximum frequency output 3V, the gain should be set to “-0.50” bias should be set to “80%.”

0: Direct start

When the DC brake time is set to 0, the inverter starts running from the starting frequency. When the DC brake time is not 0, the DC brake first, and then run from the starting frequency. Suitable for small inertia load when you start the motor may have rotated occasion.

1: Speed tracking restart of the drive motor speed and direction of the judge, and then to track the frequency of the motor start,

Rotating motor smoothly without impact start. Instantaneous power suitable for large inertia load restart. To ensure the performance speed tracking start, you need to accurately set the motor F1 group parameters.

2: Induction pre-excitation start only for asynchronous motors, used before the motor running to first establish a magnetic field. Pre-excitation current, pre-excitation time refer to the function code P6-05, P6-06 instructions.

If the pre-excitation time is set to 0, the drive to cancel pre-excitation process starts from the starting frequency. Pre-excitation time is not 0, the first and then start pre-excitation can improve the dynamic response performance of the motor.

P6-01	Speed tracking mode		Factory default	0

As to ensure that the motor torque at start-up, set an appropriate start frequency. In order to establish the full flux motor when starting, we need to start frequency to maintain a certain time.

Start from the lower frequency limit frequency P6-03. But set the target frequency is less than starting frequency, the inverter does not start, it is on standby.

Reversible switching process, starting frequency holding time does not work. Start frequency holding time is not included in the acceleration time, but is included in the running time of simple PLC.

Example 1:

P0-03=0 Frequency source is digital given

P0-08=2.00Hz Digital set frequency is 2.00Hz

P6-03=5.00Hz Starting frequency is 5.00Hz

P6-04=2.0s Start frequency holding time is 2.0s At this time, the inverter is in the standby state, the inverter output frequency is 0.00Hz.

Example 2:

P0-03=0 Frequency source is digital given

P0-08=10.00Hz Digital set frequency is 10.00Hz

P6-03=5.00Hz Starting frequency is 5.00Hz

If the DC braking time is set to 0, no start directly after DC braking. DC braking current increases, the greater the braking force.

If the startup mode for the asynchronous motor pre-excitation start, the drive set in the pre-press pre-established magnetic field current, after the set pre-magnetizing time before starting to run. If the set pre-magnetising time is 0, no pre-excitation processes started directly.

When setting frequencies above the rated frequency, acceleration and deceleration time:

$$ t = \left(\frac {4}{9} \times \left(\frac {f}{1 _ {b}}\right) ^ {2} + \frac {5}{9} \times T \right. $$

Wherein, f is set frequency, f_b is motor rated frequency, T is the time the motor nominal frequency f_b

In addition, if the parameter is set to 1, if the inverter fault reset time run command, the inverter will not run in response to a command, you must first run the command to remove the running protection status.

Setting this parameter to 1 can be prevented in the knowledge, that occur at power or fault reset, the motor operates in response to commands and cause danger.

Simple PLC function has two roles: as the frequency source or as VF separate voltage source.

Figure 6-30 is a simplified schematic diagram of the PLC as the frequency source. When simple PLC as the frequency source, PC-00 \~ PC-15 determines the direction of the positive and negative, negative if it means running the drive in the opposite direction.

Figure6-30 Schematic diagram of simple PLC

As the frequency source, PLC operates in three ways, as a voltage source does not have VF separation of these three ways. among them:

0: stop at the end of single running

The drive to complete a single cycle stops automatically give a run command to start again.

1: One end of the run to keep the value of the final drive to complete a single cycle, automatically keep running frequency and direction of the last segment.
2: After the cycle has been completed a drive cycle, the next cycle starts automatically, until the stop command to stop.

For selecting inverter control mode: Speed control or torque control.

DI VFD multifunction digital terminals, and has two functions associated with torque control: Torque control disabled (function 29), speed control / torque control switching (function 46). These two terminals keep A0-00 in conjunction to achieve switching speed and torque control.

When the speed control / torque control switch terminal is invalid, the control mode is determined by the A0-00, if speed control / torque control switch is active, the control mode is equivalent to the value of A0-00 negated.

In any case, when the torque control prohibition terminal is valid, inverter fixed speed control.

	Setting range	-200.0%~200.0%

A0-01 torque setting is used to select the source, a total of 8 torque setting mode.

Torque setting using a relative value, corresponding to 100.0% inverter rated torque. Setting range -200.0% to 200.0%, indicating that the inverter maximum torque is 2 times the rated drive torque.

When the torque setting by way of 1 to 7, communications, analog input, pulse input of 100% corresponds to A0-03.

A0-05	Torque control positive maximum	Factory default	50.00Hz
	Setting range	0.00Hz ~ maximum frequency (P0-10)
A0-06	Torque control negative maximum	Factory default	50.00Hz
	Setting range	0.00Hz ~ maximum frequency (P0-10)

It is used to set the torque control mode, the drive forward or reverse maximum operating frequency.

When the drive torque control, if the load torque is less than the output torque of the motor, the motor speed will continue to rise, in order to prevent the mechanical system appears coaster accidents, it must be limited to the maximum torque of the motor speed control.

A0-07	Torque control acceleration time		Factory default	0.00s
	Setting range	0.00s~65000s
A0-08	Torque control deceleration time		Factory default	0.00s
	Setting range	0.00s~65000s

Torque control mode, the motor output torque and load torque difference determines the speed and rate of change of the motor load, so it is possible to quickly change the motor speed, causing noise or excessive mechanical stress and other issues. By setting the torque control acceleration and deceleration time, the motor speed can be so gradual change.

However, the need for rapid response in case of torque, set the torque control acceleration and deceleration time is 0.00s. For example: Two hard-wired motor drag the same load, to ensure that the load is evenly distributed, set up a drive for the host, using the speed control mode, the drive from another machine and using the actual output torque control switch, host moments torque command as a slave, this time the torque required to follow the host machine's fast, slave torque control acceleration and deceleration time is 0.00s.

Chapter 7 EMC (Electromagnetic compatibility)

7.1 Definition

Electromagnetic compatibility means that electrical equipment operates under environment of electromagnetic interference, but it does not interfere electromagnetic environment and realizes the function stably.

7.2 Introduction of EMC standard

According to requirements of national standard GB/T12668.3, frequency convertor shall conform to requirements of two aspects: electromagnetic interference and anti-electromagnetic interference.

Our current products execute latest international standards: IEC/EN61800-3: 2004 (Adjustable speed electrical power drive systems part 3: EMC requirements and specific test methods), which is equal to national standard GB/T12668.3.

IEC/EN61800-3 mainly checks frequency convertor from two aspects: electromagnetic interference and anti-electromagnetic interference. Electromagnetic interference mainly tests radiated interference, conducted interference and harmonic interference of frequency convertor (requirements on the frequency convertor for civil use). Anti-electromagnetic interference mainly tests conduction immunity, radiated immunity, surge immunity, fast changed pulse group, ESD immunity and immunity of low-frequency terminal of power (specific test items include: 1. immunity test for input voltage sag, interruption and change; 2. immunity test for commutation notch; 3. immunity test for harmonic input; 4. change test for input frequency; 5. unbalance test for input voltage; 6. fluctuation test for input voltage). The test is conducted as per strict requirements of above IEC/EN61800-3, and please install our company products as per instructions of 7.3, which own good electromagnetic compatibility under general industry environment.

7.3 EMC guidance

7.3.1 Influence of harmonic: higher harmonic of power will damage frequency convertor, so it's suggested to install AC input reactor in the places with weak quality of power grid.
7.3.2 Electromagnetic interference and installing precautions: there are two kinds of electromagnetic interference. One is interference of surrounding electromagnetic noise for frequency convertor, and another is interference produced by frequency convertor for peripheral equipment.

Installing precautions:

1) Earthing wire of frequency convertor and other electrical products should be well grounded;
2) Do not layout power input and output line or weak current signal line (e.g. control circuit) of frequency convertor in parallel, layout them vertically if possible;
3) It's suggested to use shield cable or steel tube shield power line for output power line of frequency convertor, and keep reliable earthing of shield layer. For the lead of equipment with interference, it's suggested to use dual twisted pair shield control line and keep reliable earthing of shield layer;
4) For the motor cable exceeding 100m, output filter or electric reactor should be installed.

7.3.3 Handling method of interference produced by peripheral electromagnetic equipment for frequency convertor: in general, the cause of frequency convertor produces electromagnetic influence is that many relays, contactors or electromagnetic brakes are installed nearby frequency convertor. If any malfunction of frequency convertor due to interference, it's suggested to adopt below methods:

1) The devices producing interference are installed with surge suppressor;
2) Install filter in input terminal of frequency convertor as per 7.3.6 for operation;

3) Control signal line and lead of detection circuit adopt shield cable, and keep reliable earthing.

7.3.4 Handling method of interference produced by peripheral equipment for frequency convertor: there are two kinds of noise, namely radiated interference of frequency convertor and conducted interference of frequency convertor. These two interference lead to electromagnetic or electrostatic induction of peripheral electrical equipment, and then cause malfunction of equipment. Aiming at different interference, below solutions can be referred:

1) The signal of instruments, receivers and sensor for measurement is generally weak. If they are

near to frequency convertor or in the same control cabinet, the frequency convertor is easily interfered and malfunction produces. It's suggested to adopt below solutions: keep away from interference source as far as possible; do not layout signal line and power line in parallel, or bundle up them in parallel; signal line and power line adopt shield line, keep reliable earthing; install ferrite core (range of blanketing frequency is 30\~1000MHz) on output side of frequency convertor and wind 2\~3 turns in the same direction. For serious situation, EMC output filter can be installed;

2) If interfered equipments share the same power with frequency convertor, conducted interference will produce. If interference can't be eliminated through above method, EMC filter shall be installed between frequency convertor and power (refer to 7.3.6 for model selection operation);
3) Independent earthing of peripheral equipment can eliminate the interference produced by leak current of ground lead of frequency convertor.

7.3.5 Leak current and handling: there are two kinds of forms of leak current when using frequency convertor: leak current to ground, and leak current between lines.

1) Factors influencing leak current to ground and solutions:

There is distributed capacitance between wire and ground. The larger the distributed capacitance, the larger the leak current will be, so reduce the distance between frequency convertor and motor to decrease distributed capacitance. The larger the carrier frequency, the larger the leak current will be, so decrease carrier frequency to reduce leak current. However, decreasing carrier frequency will lead to increasing motor noise. Please note that installing reactor is an effective way to solve leak current.

Leak current increases with enlargement of loop current, so the larger the motor power, the larger the corresponding leak current will be.

2) Factors influencing leak current between lines and solutions:

There is distributed capacitance between output wiring of frequency convertor. If the current passing circuit contains higher harmonic, resonance may be caused to produce leak current. If using thermal relay at this time, malfunction may occur.

The solution is to reduce carrier frequency or install output reactor. When using frequency convertor, it's not suggested to install thermal relay between frequency convertor and motor, but use electric over-current protection function of frequency convertor.

7.3.6 Precautions about installing EMC input filter on power input terminal:

1) Caution: please strictly abide by rated value when using filter. As filter is I-class electric appliance, metal shell of filter should contact well with metal of installing cabinet, and good electric conduction continuity is required, otherwise there is risk of electric shock and EMC effect will be seriously influenced;
2) According to EMC test, filter and PE terminal of frequency convertor should be connected on the same ground, otherwise EMC effect will be seriously influenced;
3) The filter should be installed nearby power input terminal of frequency convertor as far as possible.

Chapter 8 Fault diagnosis and countermeasures

8.1 Fault warning and countermeasures

Frequency convertor owns 24 warning information and protection functions. Once the fault occurs, protection function starts action and the frequency convertor stops output. Fault relay of frequency convertor starts contact action and fault code displays on display panel of frequency convertor. Before users seek for service, they can examine by themselves as per instructions in this chapter to analyze fault cause and find out solutions. If the causes are those in dotted line box, please seek for service and contact with agent of frequency convertor or our company directly.

Appendix F: VFD-Modbus communication protocol

This series frequency convertor provides RS232/RS485 communication interface and supports Modbus communication protocol. Users can realize centralized control through computer or PLC, set run command of frequency convertor through communication protocol, modify or read parameters of function code, read working condition and fault information of frequency convertor, etc.

I. Protocol content

The serial communication protocol defines transmissive information contents and using format of serial communication, including format for polling of host (or broadcast), encoding method of host such as function code of required action, transmission data and error verification, etc. The response of slave also adopts same structure and the contents include action confirmation, data return and error verification, etc. If any error of slave when receiving information or failure to finish the action required by host, the slave will organize a fault message as response feedback for the host.

Application mode: frequency convertor accesses to “single-host and multiple-slave” PC/PLC control network with RS232/RS485 bus.

Structure of bus

(1) Interface mode

RS232/RS485 hardware interface

(2) Transmission mode: asynchronous serial and half-duplex. For the host and slave at the same moment, one can only send data and another can only receive data. During serial asynchronous communication process, data is sent with the form of message frame by frame.

(3) Topological structure: single-host and multiple-slave system. The setting range of slave address is 1\~247 and 0 is address of broadcast communication. Slave address in network should be unique.

Protocol description

Communication protocol of this series frequency convertor is a kind of asynchronous serial master-slave Modbus communication protocol, and only one device (host) in the network can establish protocol (called as "query/command"). Other devices (slave) can only response the "query/command" of host by providing data or take corresponding actions based on "query/command" of host. Host refers to personal computer (PC), industrial control equipment or programmable logic controller (PLC), etc, and slave means this series frequency convertor. The host can not only communicate with certain slave separately, but issue broadcast information to all inferior slaves. For separately accessed "query/command" of host, the slave needs to return a message (called as response). For the broadcast information issued by the host, the slave does not need to feedback response to host.

Structure of communication materials: communication data format of modbus protocol for this series frequency convertor is as below:

For RTU mode, message sending starts with pause time for at least 3.5 characters. Diverse character time under network Baud rate is easily realized (as shown in below T1-T2-T3-T4). The first domain of transmission is equipment address.

The available transmission character is hexadecimal 0...9, A...F. Network equipment detects network bus constantly, including pausing interval time. When receiving first domain (address domain), each equipment will decode to judge if sending to own. After the last transmission character, the pause time of at least 3.5 characters marks the ending of message. A new message will start after the pause.

The whole message frame should be continuous streaming transfer. If the dwell time exceeds 1.5 characters before frame finishes, receiving equipment will refresh incomplete message and assume that next byte is address domain of a new message. Similarly, if a new message starts within time of 3.5 characters following previous message, receiving equipment will consider it as the delay of previous message, and then error will be caused, as it's impossible for the value of final CRC domain to be correct.

RTU frame format

Frame header START	Time of 3.5 characters
Slave ADR Address	1~247
CMD code	03: read slave parameters; 06: write slave parameters
DATA (N-1)	Data content: address of function code parameters, number of function code parameters, value of function code parameters, etc

Verification mode-CRC verification mode: CRC (Cyclical Redundancy Check) uses RTU frame format, and message includes error detection domain based on CRC method. CRC domain detects the contents of whole message. CRC domain is two-byte and includes 16-bit binary system value. It's added to message after calculation by transmission equipment. Receiving equipment recalculates CRC of received message and compares with value in received CRC domain. If two CRC values are not equal, the transmission is wrong.

CRC firstly stores 0xFFFF, and then calls a course to process successive 8-bit bytes in message and value in current register. Only 8Bit data in each character is valid for CRC, start bit, stop bit and parity check bit are invalid.

During producing process of CRC, each 8-bit byte is XOR with register contents separately. Finally, it moves to the direction of least significant bit, and most significant bit is filled with 0. LSB is extracted for detection. If LSB is 1, register is XOR with preset value. If LSB is 0, no action. Repeat the whole process for 8 times. After last bit ( 8^th bit) finishes, next 8-bit byte is XOR with current value of register alone. The final value in register is CRC value after all bytes in message are executed.

When adding CRC to message, add low byte firstly and then high byte. Simple function of CRC is as below:

unsigned int crc_chk_value (unsigned char *data_value, unsigned char length) {
    unsigned int crc_value=0xFFFF;
    int i;
    while (length--) {
    crc_value^=*data_value++;
    for (i=0;i<8;i++) {
    if (crc_value&0x0001)
    {
    crc_value= (crc_value>>1)
    }
    else crc_value=crc_value>>1;
    {
    }
    }
    }
    return (crc_value);
} 

Address definition of communication parameter

This part is communication content used for controlling operation of frequency convertor, setting state and related parameters of frequency convertor.

Read-write function code parameter (some function codes can't be modified, but are simply used or monitored by manufacturer).

Marking rules of function code parameter address:

Express rules with group No. and marking No. of function code being parameter address:

High byte: P0\~PF (P group), A0\~AF (A group), 70\~7F (U group); low byte: 00\~FF

E.g.: P3-12, address is expressed as P30C;

Note: PF group: neither read nor modify parameters;

U group: only read but not modify parameters.

When the frequency convertor is in running status, some parameters can't be modified. Some parameters can't be modified no matter what is the status of frequency convertor. When modifying the function code parameters, range, unit and related descriptions of parameters should be also noticed.

Besides, as EEPROM is frequently stored, it will reduce lifespan of EEPROM. Therefore, under communication mode, some function codes don't have to be stored, and only modify the value in RAM.

If it's P group parameter, changing high-order F of the function code address to be 0 can realize the function. If it's A group parameter, changing high-order A of the function code address to be 4 can realize the function. Corresponding function code address is expressed as below: high-order byte: 00\~0F (P group), 40\~4F (A group); low-order byte: 00\~FF

E.g.: function code P3-12 is not stored in EEPROM, the address is expressed as 030C; function code A0-05 is not stored in EEPROM, the address is expressed as 4005; the address can only write RAM and conduct read action. When reading, it's invalid address. For all parameters, CMD code 07H can also be used to realize the function.

When the frequency convertor is in running status, some parameters can't be modified. Some parameters can't be modified no matter what is the status of frequency convertor. When modifying the function code parameters, range, unit and related descriptions of parameters should be also noticed.

For frequency dimension, this percent is the percentage of relatively largest frequency (P0-10). For the data of torque dimension, this percent is P2-10, A2-48, A3-48, A4-48 (upper limit setting of torque respectively corresponds to first and second motor).

Description of PD group communication parameters

Pd-00	Baud rate	Factory default	6005
	Setting range	Unit: MODUBS Baud rate0: 300BPS1: 600BPS2: 1200BPS3: 2400BPS4: 4800BPS5: 9600BPS6: 19200BPS7: 38400BPS8: 57600BPS9: 115200BPS

The parameter is used to set data transmission rate between host computer and frequency convertor. Please note that the Baud rate of host computer and frequency convertor should be consistent. Otherwise, communication is unable to proceed. The larger the Baud rate, the faster the communication speed.

Fd-01	Data format	Factory default	0
	Setting range	0: no verification: data format <8,N,2>1: even verification: data format <8,E,1>2: odd verification: data format <8,O,1>3: no verification: data format <8-N-1>

The data format of host computer and frequency convertor should be consistent. Otherwise, communication is unable to proceed.

Pd-02	Local address	Factory default	1
	Setting range	1~247, 0 is broadcast address

If local address is set as 0, namely broadcast address, broadcast function of host computer can be realized.

Local address is unique (apart from broadcast address), and it's the basis to realize point-to-point communication between host computer and frequency convertor.

Pd-03	Response delay	Factory default	2ms
	Setting range	0~20ms

Response delay: interval time between ending time of data reception of frequency convertor and time of sending data of host computer. If response delay is shorter than system processing time, response delay takes system processing time as criterion. If response delay is longer than system

processing time, delay await is required after system processes data. After reaching response delay time, data will be sent to host computer.

Pd-04	Communication overtime	Factory default	0.0 s
	Setting range	0.0 s (invalid)0.1~60.0s

If function code is set to be 0.0s, parameter of communication overtime is invalid.

If function code is set to be valid value, interval time between one communication and next communication exceeds communication overtime, the system will give alarm of communication fault (Err 16). Under normal conditions, it's set to be invalid. If setting subparameter in the system of continuous communication, communication status can be monitored.

Pd-05	Communication protocol Factory default	0
	Setting range	0: non-standard Modbus protocol1: Standard Modbus protocol

PD-05=1: select standard Modbus protocol.

PD-05=0: when reading command, number of bytes returned by slave has one more byte than standard Modbus protocol. See details in “5 communication data structure” of the protocol.

Pd-05	Communication reads current resolution	Factory default	0
	Setting range	0: 0.01A1: 0.1A

It's used to confirm output unit of current value when communication reads output current.
