Speed controller for asynchronous motors

Page 34

When the speed controller has power on, a number of components are connected to the supply. It is extremely dangerous to touch them.

After switching off the supply to the Altivar wait for 1 minute before touching the equipment. This is the time taken for the capacitors to discharge.

During operation the motor can be stopped or started by inhibiting the start command with the speed controller still connected to the supply. For personnel safety during maintenance electronic locking should not be used, the supply should be switched-off.

The speed controller incorporates safety devices which can shutdown the speed controller and stop the motor in the event of a fault. These faults may be caused by a mechanical blockage of the motor or alternatively problems with the electrical supply.

The removal of the problem may cause the motor to re-start, creating danger for certain machines and installations, especially those which must conform to safety regulations.

In such cases, therefore, the user must take precautions to avoid re-starting of the motor. A device such as a speed detector should be incorporated to remove the supply in the event of an unscheduled stopping of the motor.

The equipment has been designed to conform to IEC standards.

In general, power to the speed controller must be switched off before any electrical or mechanical intervention on the installation or machine.

The products and materials presented in this document may be changed or modified at any time, either from a technical point of view or in the way they are operated. Their description can in no way be considered contractual.

Warning

The Altivar 18 must be considered a component. It is neither a machine nor a piece of equipment ready for use in accordance with European directives (machinery directive and electromagnetic compatibility directive). It is the responsibility of the user to ensure that his machine meets these standards.

This speed controller must be installed and set up in accordance with international and national standards. This compliance is the responsibility of the systems integrator who must respect the European community EMC directive amongst others.

(1) Typical value without additional inductance.
(2) For 60 seconds.

The Altivar 18 is designed to supply the required power for the appropriate motor.

Continuous operation

For self-ventilated motors, motor cooling is linked to speed. Derating occurs at speeds of less than half the nominal speed.

Operation in overspeed

Since the voltage can no longer change with the frequency, there is a decrease in motor induction resulting in a loss of torque. Consult the manufacturer to find out whether the machine can operate in overspeed.

Torque characteristics :

1 Continuous usable torque : self-ventilated motor
2 Continuous usable torque: force-ventilated motor
3 Transient overtorque : typical curve at ± 10 % Value : 1.5 Tn for 60 s

Note : With a special motor, the nominal frequency and the maximum frequency can be adjusted from 40 to 320 Hz .

Mounting recommendations

Mount the unit vertically.

Avoid placing close to any heating equipment.

Leave enough free space to ensure that sufficient air can circulate for cooling. The unit is ventilated from the bottom upwards.

IP20 : remove the blanking cover from the top (self-adhesive film).

Ventilation flow rate

ATV-18U09M2, U18M2, U18N4 : not ventilated.

ATV-18U29M2, U29N4:0.25 m³/minute.

ATV-18U41M2, U54M2, U72M2, U41N4, U54N4, U72N4: 0.75 m³/minute.

ATV-18U90M2, D12M2, U90N4, D12N4, D16N4, D23N4 : 1.3 m³/minute.

Observe the mounting recommendations given on page 41.

To ensure air circulation in the speed controller :

• provide ventilation louvres,
• ensure that ventilation is sufficient. If not install forced ventilation with a filter,
• use special filters in IP 54,
• remove the blanking cover from the top of the speed controller.

Dust and damp proof metal enclosure (degree of protection IP 54)

The speed controller needs to be mounted in a dust and damp proof enclosure under certain environmental conditions : dust, corrosive gas, high humidity with a risk of condensation or dripping water, splashing liquid, etc.

To avoid hot spots in the speed controller, if it is a non-ventilated model, add a fan to circulate the air inside the enclosure.

This means that the speed controller can be used in an enclosure where the maximum internal temperature can reach 50^ .

Calculating the size of the enclosure

Maximum thermal resistance Rth (^ / W) ..

$$ R t h = \begin{array}{c c} \theta^ {\circ} - \theta^ {\circ} e & \theta^ {\circ} \ P & \theta^ {\circ} e \end{array} = \begin{array}{c c} \text {m a x i m u m t e m p e r a t u r e i n t h e e n c l o s u r e i n} ^ {\circ} C, \ \text {m a x i m u m e x t e r n a l t e m p e r a t u r e i n} ^ {\circ} C, \ P & \text {t o t a l p o w e r d i s s i p a t e d i n t h e e n c l o s u r e i n} W. \end{array} $$

Power dissipated by the speed controller : see page 38.

Add the power dissipated by the other equipment.

Useful heat dissipation surface of the enclosure S (^2) ..

(sides + top + front, when the controller is wall-mounted)

$$ S = \frac {K}{R t h} \quad K = \text {t h e r m a l r e s i s t a n c e p e r} m ^ {2} \text {o f t h e e n c l o s u r e}. $$

For a metal enclosure: K = 0.12 with an internal fan,

K = 0.15 with no fan.

Warning : Do not use insulated enclosures, as they have a poor level of conductivity.

Installation : to comply with standards EN55011 class A, EN61800-3, IEC1800-3.

General rules

• Grounds between speed controller, motor and cable shielding must have "high frequency" equipotentiality.
• Use shielded cables with shielding connected to the ground at 360^ at both ends of the motor cable and the control cables. This shielding can be conduit or metal ducting as long as there is no break in continuity.

Installation diagram

1- Mounting plate, unpainted flat sheet steel, with anti-corrosion treated conductors (machine ground wiring).

Painted steel can be used on condition that good electrical contact is ensured between the mounting surfaces with 2 and 5.

2- Altivar 18 fixed directly to the mounting plate (equipotential grounds).
3- Non-shielded supply wires or cable for connecting the line choke, if used.
4- Non-shielded wires for fault relay contact output wires.
5- The shielding for cables 6 and 7 should be fixed and grounded as close to the controller as possible :

strip the shielding,
- use the correct size clamps on the stripped parts of the shielding to fix to the backplate,
-type of clamps : stainless steel.

The shielding must be clamped tightly enough to the backplate for the contacts to be good.

6- Shielded cable for connecting the motor, with shielding connected to ground at both ends.

This shielding must be uninterrupted, and any intermediate terminal blocks must be in an EMC shielded metal case.

7- Shielded cable for connecting the control/command system.

For uses which may require several conductors, small cross sections should be used (0.5mm^2) .

The shielding must be connected to ground at both ends. This shielding must be uninterrupted, and any intermediate terminal blocks must be in an EMC shielded metal case.

Note : The HF equipotential ground connection between speed controller, motor and cable shielding does not remove the need to connect the protective conductors PE (green-yellow), to the appropriate terminals on each of the units.

Accessing terminal blocks

To access terminal blocks, remove cover fixed by 2 screws.

Terminal blocks : on the lower part of the Altivar.

1 - Control
2 - Power
3 - Terminal for connecting a protection conductor with a 10mm^2 cross section in accordance with EN50178 (earth leakage current)

Speed controllers are fitted with metal gland plates equipped with rubber blanking plugs which can be perforated to enable cables to be passed through them and also to protect the cables. The gland plates can take EMC metal cable glands.

Choice of associated components

See Altivar 18 catalog.

Wiring recommendations

Power

Follow the cable cross-section recommendations specified in the standards.

The speed controller must be earthed, in order to comply with regulations concerning high leakage currents (over 3.5mA ). Upstream protection by differential circuit-breaker is not advised as DC elements may be generated by leakage currents from the speed controller. If the installation has several speed controllers on the same supply, connect each speed controller to earth separately. If necessary, provide a line choke (consult the catalogue).

Keep the power cables apart from low-level signal circuits (detectors, PLCs, measuring equipment, video, telephone).

Control

Keep the control circuits and the power cables apart. For control circuits and speed reference circuits, it is advisable to use a shielded, twisted pair cable at intervals of between 25 and 50mm by connecting the shielding at each end.

Fault relay, resetting

The fault relay is energized when the speed controller is powered up and not faulty. It comprises a C/O contact.

The speed controller is reset after a fault :

• by switching it off until the display and the red indicator lamp disappear and then restarting the speed controller,
• automatically in the cases described under the "automatic restart" function.

Thermal protection of the speed controller

Function :

Protection via a thermistor fixed to the heatsink.

Indirect protection of the speed controller by calculating the l^2 t .

This function ensures thermal protection of the speed controller in normal ambient temperature conditions.

Typical tripping points :

• motor current = 185% of the nominal speed controller current : 2 seconds,
• motor current = 150% of the nominal speed controller current : 60 seconds,
• motor current ≤ 110% of the nominal speed controller current : does not trip.

Possible deratings for switching frequencies of >4kHz are automatically taken into account and reduce the admissible I^2t .

Warning : If the speed controller is switched off, the I²t calculation is reset to 0 .

Speed controller ventilation

For models which have a fan, the fan is supplied automatically when the speed controller is reset (operating direction + reference). It is switched off several seconds after the speed controller is locked (motor speed < 0.5Hz and injection braking completed).

Logic inputs

• LI1: forward operation. Cannot be assigned to another function.

When the contact is closed, the frequency setpoint is applied in the forward direction.

• LI2, LI3, LI4 : can be assigned to the following functions :

• reverse direction: r 5 assignment

When the contact is closed, the frequency setpoint is applied in reverse direction. If LI1 is also closed, the first one to have been closed has priority.

-2 speeds: P5 assignment

Open contact: reference = L 5 P + analog reference.

Closed contact : reference = H 5 P .

• 4 speeds : assignment of one input to P ≤ 2 and another to P ≤ 4 (it is not possible to assign P ≤ 4 only)

K1 and K2 open: setpoint = L P + analog setpoint.
K1 closed and K2 open: setpoint = 5P (level 1 adjustment).
K1 open and K2 closed: setpoint = 5P4 (level 1 adjustment).
K1 and K2 closed: setpoint = H5P

Logic and analog input functions which can be configured

• JG: jog operation. JG assignment

If the contact is closed and then operating direction contact is also closed, the ramp time is 0.1 s irrespective of the R C and d C settings. If the speed controller is already operating and the contact assigned to J G is closed, the ramp times are those of R C and d C . The minimum time between two J G operations is 0.5 s.

Note: 1- During "jog" operation, automatic DC injection braking when the motor is stopped is inhibited. 2- Injection braking on the logic input has priority over operation.

• Fast stop: F S E assignment

Note : Fast stop command is activated when the contact between the input and the + 24 V is open.

Braked stop, with the dE ramp time divided by 4, but limited to the acceptable minimum without locking on an "excessive braking" fault (self-adaptation if the braking capability is exceeded).

Note : During fast stop, braking either by automatic DC injection or on the logic input is inhibited.

• DC injection braking: dL assignment

Note : Injection braking command is activated when the contact between the input and the +24V is closed.

The braking current is equal to the speed controller nominal current during 5 seconds. After 5 seconds, braking current is peak limited to a maximum value of 0.5 I E H motor.

Note : 1- Automatic injection braking when stopped remains active if the d C I function is assigned. 2- Fast stop has priority over injection braking.

Analog inputs

An extra analog input can be used as :

• voltage on Al2,
• current on AIC.

and can be assigned as :

• a summing input of AI1,
• PI regulator feedback.

Summing with AI1:5R/ assignment

PI regulator feedback : P IF assignment

This assignment automatically configures AI1 as a reference for the PI regulator.

Adjustment parameters r , P , r , I , and F , B are in level 1.

• AIC parameter setting: 0 - 20mA or 4 - 20mA .

Note : The PI function is not compatible with certain logic input functions :

• preset speeds (2 or 4),
  -jog operation ( )

The choice of application selections is restricted due to incompatibility between certain functions. Those functions which are not listed can be used without restriction.

Non-compatible functions Compatible functions not significant

Function priority (Functions unable to be used at the same time) :

The function indicated by the arrow has priority over the other one.

The first operated has priority.

The choice of functions is limited by the number of configurable logic inputs (3). Functions using configurable logic inputs :

• One input for each function: reverse direction, D.C. braking, fast stop, jog, 2 preset speeds.
• Two inputs for the function : 4 preset speeds.

The Altivar is factory preset for standard applications :

• applications with constant torque.

Preset values

• Display : speed controller ready (when stopped), motor frequency (in operation).
• Supply: 50 Hz.
• Motor voltage: 230V or 400V , depending on the product.
• Ramps : 3 seconds.
• Low speed: 0 Hz - High speed: 50 Hz.
• Frequency loop gain : standard.
• Thermal motor current = nominal speed controller current.
• Injection braking current when stopped = 0.7 nominal speed controller current, for 0.5 seconds.
• Operation at constant torque, with sensorless flux vector control.
• Logic inputs :

.2 operating directions (LI1, LI2),
.4 preset speeds (LI3, LI4): 0 Hz, 5 Hz, 25 Hz, 50 Hz.

• Analog inputs :

. Al1 : speed reference 0 + 10 V ,
. Al2 (0 + 10V) or AIC (0,20mA) summing of Al1.

• Logic output :
  . LO : speed reference reached.
• Automatic adaptation of the deceleration ramp if there is overvoltage on braking.
• Switching frequency of 4kHz

If the above values are compatible with the application, the speed controller can be used without modifying the settings.

In power control with line contactor :

• avoid frequent operation of contactor KM1 (premature ageing of capacitors), use inputs LI1 to LI4 to control the speed controller,
• in the case of cycles < 60 s, these measures are essential, otherwise the load resistor may be destroyed.

User adjustment and function extensions

If necessary, the display can be used to make adjustments and to expand the functions using those listed on the following pages. There are two levels of access:

• level 1: adjustments (standard configuration),
• level 2: extension of functions.

It is easy to return to the factory setting.

There are three types of parameter :

• display : values displayed by the speed controller,
• adjustment : can be modified during operation or when stopped,
• configuration : can only be modified when stopped and with no braking. Can be displayed during operation.

• ensure that the setting changes made during operation present no danger. It is advisable to perform modifications when the machine has stopped.

R E r	Automatic restart, after locking on fault, if the fault is no longer present and the other operating conditions allow. To restart, a series of automatic attempts are performed at increasing intervals : 1 s, 5 s, 10 s, then 1 min for subsequent attempts. If the start has not been achieved after 6 min, the procedure is abandoned and the speed controller remains locked until it is switched off and then switched on again. The faults which enable this function are : DH , DL , USF , ObF , OSF. The fault relay of the speed controller then remains activated if the function is active. The speed setpoint and the operating direction must be retained.

Before performing any operation on the speed controller, switch off the power supply and wait for the capacitors to discharge (takes approximately 1 minute). The red indicator lamp should be off.

DC voltage to terminals PA and PB and hidden terminals PO, PC can reach 800 to 900 V depending on the mains voltage.

In case of a fault during installation or operation, firstly ensure that the guidelines relating to the environment, mounting and connections have been followed.

Maintenance

The Altivar 18 does not require any preventive maintenance. However, the user is advised to do the following at regular intervals :

• check the state and tightness of connections,
• ensure that the temperature in the area around the equipment remains at an acceptable level, and that ventilation is effective (average lifetime of fans: 3 to 5 years depending on the conditions of use),
• ensure the speed controller is free from dust.

Maintenance assistance

The first fault detected is memorized and displayed on the display if the voltage is maintained : the speed controller locks itself and the fault relay trips.

Clearing the fault

Remove the power supply to the speed controller.

Find the cause of the fault in order to eliminate it.

Reconnect the power supply : this will clear the fault if it has been corrected.

In some cases the equipment may automatically restart after the fault has disappeared, if this function has been programmed.

Replacements and repairs

For repairs and replacements on Altivar 18 speed controllers, consult your local Schneider office.

Faults which can be reset with the automatic restart function, after the cause of the fault has been corrected

Fault	Probable cause	Remedies
☐ HF speed controller overload	- I²t too high or - speed controller temperature too high	- Check the motor load, the speed controller ventilation and the environment. Wait for it to cool before restarting.
☐ L F motor overload	- I²t motor too high	- Check the setting of the motor thermal protection, and check the motor load. Wait for it to cool before restarting.
☐ 5 F overvoltage in steady state or during acceleration	- mains voltage too high - mains interference	- Check the mains voltage.
U 5 F under voltage	- Mains supply voltage too low - Momentary drop in voltage - Weakened load resistance	- Check the voltage and the voltage parameter. - Reset. - Change the load resistance.
