How to troubleshoot configuration or communication error on Gefran Inverter?
S
Shannon LynnSep 2, 2025
If the Gefran Inverter displays an error in the configuration stage or communication error, and if the first digit to the left of “H” in the alarm sub-code is equal to 0, the error relates to a communication problem. If the first digit to the left of “H” in the alarm sub-code is other than 0, the error relates to a configuration problem. For configuration errors, check the configuration of the Bus communication, Bus type, Baudrate, address parameter setting. For communication errors, verify wiring, resistance of terminations, interference immunity, timeout settings.

How to fix DC link overvoltage on gefran ADP200 Inverter?
D
David DelgadoAug 23, 2025
If the Gefran Inverter shows a DC link overvoltage alarm, which indicates energy recovered from the load is too high, you can try the following:
- Extend the deceleration ramp.
- Use a braking resistor between terminals BR1 and BR2 to dissipate the energy.
- Use the VDC Control function.
This issue occurs when the voltage arriving at the drive power section exceeds the maximum threshold related to the PAR 560 Mains voltage parameter setting.

Why Gefran Inverter displays Motor overtemperature alarm?
C
Cindy RodriguezAug 30, 2025
If the Gefran Inverter shows a motor overtemperature alarm, it can be due to several reasons:
- Load cycle too heavy.
- The motor is installed in a place where the ambient temperature is too high.
- If the motor is provided with a blower: the fan is not working.
- If the motor is not provided with a blower: the load is too high at slow speeds.
- The motor is used at less than the rated frequency, causing additional motor heating.
To resolve this:
- Change the processing cycle.
- Use a cooling fan to cool the motor.

How to fix Drive overload alarm on gefran ADP200?

Mark FloresAug 28, 2025
If your Gefran Inverter displays a Drive overload alarm, it means the inverter output current has exceeded the allowed overload value, or the overload cycle has exceeded the allowed values. To resolve this:
- Check that the load is not excessive.
- Check that accelerations are not excessive.
- Check that the overload cycle is within allowed limits.

How to resolve braking resistor overload alarm on gefran ADP200 Inverter?
H
Harold DavisAug 27, 2025
If you're getting a braking resistor overload alarm on your Gefran Inverter, it means that the current absorbed by the resistor is greater than the rated current, or the overload threshold of the accumulator of the I²t braking resistor thermal image has been exceeded. You should:
- Check the size of the braking resistor.
- Check the condition of the braking resistor.
- Use a braking resistor with higher energy value and change the parameters on 22.5 - FUNCTIONS/BRES OVERLOAD menu.

What causes motor overload alarm on Gefran Inverter?
C
Carolyn SweeneyAug 26, 2025
If your Gefran Inverter displays a motor overload alarm, it means the current absorbed during operation is greater than that specified on the motor data plate. To solve this:
- Reduce the motor load.
- Increase the size of the motor.

Why gefran ADP200 shows DC link undervoltage alarm?
J
James WalkerAug 26, 2025
If your Gefran Inverter shows a DC link undervoltage alarm, check the connections. The problem is caused by the voltage arriving at the drive power section being too low compared to the Undervoltage [UV], the mains voltage being too low or overextended voltage drops, or poor cable connections (e.g. loose contactor terminals, inductance, filter).
