Frequently Asked Questions - A2-8075 Vevor

What is the input voltage of the Vevor A2-8075 inverter?

The inverter accepts a single-phase or three-phase input of 220 V. The output is always three-phase 220 V.

How to configure the output frequency?

You can adjust the frequency via the panel potentiometer, the ▲/▼ buttons, or by external signals (0-5V, 0-10V, 0-20mA). Parameter Pn03 allows you to select the frequency source.

What to do if the inverter displays error OU-o (overvoltage)?

Error OU-o indicates an overvoltage of the power source. Check the input voltage with a voltmeter and ensure it is within the allowed range (220 V ±10%).

How to change the acceleration and deceleration times?

Use parameters Pn08 (acceleration time) and Pn09 (deceleration time). Values can be set from 0.01 s to 50.00 s via the control panel.

Can I control the inverter remotely?

Yes, set Pn04=2 for control by external signals via the FWD/REV terminals, and Pn03 for external frequency source. Analog inputs (0-5V, 0-10V, 0-20mA) and digital inputs (multi-speed) are available.

How to perform DC braking?

DC braking is configurable via parameters Pn15 to Pn18. Set the voltage (1-100V) and duration (0-650s) for start and stop braking to prevent free movement of the motor.

What is the reset procedure after a fault?

Press the RESET button (STOP/RESET) to clear the fault. If the error persists, cut off the power, wait 10 minutes, then check the connections and parameters.

How to maintain the inverter to extend its lifespan?

Regularly clean dust with a vacuum cleaner, check the tightness of terminal screws, and ensure adequate ventilation. Replace the cooling fan (every 20,000-40,000 h) and the electrolytic capacitors (every 30,000-50,000 h).

Can the inverter be used with a single-phase motor?

No, this inverter is designed for three-phase motors. The output is three-phase 220 V. Do not connect a single-phase load to terminals U, V, W.

How to configure multi-speed?

Set Pn03=7 (multi-speed frequency source) and Pn04=2 (external control). Use inputs D0, D1, D2 to select up to 8 preset speeds via parameters Pn20 to Pn27.

Pn 33 Software version

Pn 34 Auto recover while lost power suddenly0 disable this function 99 means do auto recover in infinite time, starting from low frequency Other value:

If indicator displays LU-X(any code) during runtime and power source recovers in 2 seconds, inverter would start up again and reduce runtime frequency with magnitude of under voltage time(s) multiply frequency of this component(Hz).

The maximum power lost time is 2.5s. Beyond this time, it would be seen as over voltage without any auto recover.

8. Operation Examples

8.1 Operation by panel

Pn 04 = 1 (Command from panel), Pn 03 = 1 (Frequency from potentiometer)

Push button “RUN” on the panel, inverter starts up and running indicator is on.

Push the button again, inverter would stop.

8.2 Operation by external signal

Pn 04=2 (command from port "FWD/REV")

Pn 03=3 (frequency from port "5V")

8.3 Multi-segment speed

Pn 04=2(command from port "FWD/REV")

Pn 03=7 (frequency from multi-segment 0-7)

8.4 Point move by panel

Command (Pn 04) must come from panel (=1). Frequency (Pn 03) must be specified by button (=2). After inverter stops, push button “←” to clockwise point move and “→” to anticlockwise point move.

8.5 Point move by external signal

Command (Pn 04) must come from port "FWD/REV" (=2).

Frequency (Pn 03) must come from external digital port (=6). After inverter stops, connect "D0" and "JOG" to "GND" to point move

9.2 Other unexpected fault

1. Inverter is in normal condition but without any output
2. Internal fuse fail
3. Internal drive module fail

10. Maintenance and Repair

Due to the environment influence such as temperature, humidity, dust and vibration etc., and aging component, inverter may be fail at some time. So it needs periodic maintenance and repair.

Notice: please check the following items before maintenance and repair.

Otherwise, it may cause electric shock.

1. Power source is cut off.
2. Indicator on panel is OFF.
3. Maintenance is performed by professionals.

10.1 Daily maintenance and repair

The inverter must be installed in the standard environment according to this manual. There may be some unexpected situations during runtime. Please perform daily maintenance according to the following table. Keep a good runtime environment, log daily data, and detect fault causes early. This can extend the life of the inverter.

Item	Check			Criterion
	Content	Period	Method
environment	(1) temperature, humidity(2) dust, water(3) corrosive gas	anytime	(1) thermometer, hygrometer(2) watch(3) smell	(1) temperature range 10°C ~+40°C(2) any mark of water(3) odor

motor	(1) heat(2) noise	anytime	(1) touch(2) sound	(1) abnormal heating(2) abnormal sound

10.2 Periodic maintenance

The inverter needs periodic maintenance every 1 or 3 months, depending on the runtime environment.

Notice: Machine maintenance or component replacement must be performed by professionals. If any metal objects such as screws or washers are left inside the machine, it could cause fatal damage to the inverter!

Check items:

1. Whether the control port screws are loose or not;
2. Whether the main loop ports are loose or not. Or is there any sign of overheating in the line of the main loop;
3. Is there any trauma in power and control cables. Especially, check the rubber skin in contact with other metal;
4. Is the insulation bandage of the power cable loose;
5. Use a vacuum cleaner to clean dust on the board and ventilation channel.
6. If the motor needs examination, please disconnect the motor wire from the inverter's U, V, W ports. Otherwise, it may cause fatal damage to the inverter.

Notice: The inverter has already passed the pressure test. Any improper test may cause fatal damage to the inverter!

10.3 Replace the wearing parts

The wearing parts include the cooling fan and filter electrolytic capacitor, whose lifetime depends on environment and load. When the temperature is 25°C, the lifetime of the cooling fan is 20~40Kh and that of the capacitor is 30~50Kh. The user can decide when to replace these components.

1. Cooling fan

Cause of damage: worn bearing, aging fan, heavy dust environment. Criterion: rips in fans, abnormal vibration during runtime.

2. Filter electrolytic capacitor

Cause of damage: high environment temperature, frequent load changes, long-time full load.

Criterion: liquid leak, wrong position of safety valve, capacity measurement.

10.4 Storage of inverter

Precautions for storing the inverter:

1. It cannot be stored in high temperature, moist, dusty, metal dust, or corrosive gas places.
2. It will speed up the capacitor aging during long-time storage. Make sure to turn on the inverter once every year. The operation time cannot be below 8 hours. And the input voltage increases slowly to the rating value.

10.5 Warranty

Range: inverter itself;

If any of the following situations occur, Isacon will provide warranty:

Any fault or damage that occurs during standard use within 18 months.

Beyond 18 months, Isacon will charge for maintenance and repair. If any of the following situations occur, even within 18 months, Isacon may still charge for maintenance and repair:

A. Damage caused by incorrect operation; B. Damage caused by abnormal voltage or natural disasters such as fire and floods, etc.; C. Use of the inverter in non-standard applications.

Costs will be calculated as per the contract or actual costs.
