How to fix DC link overvoltage alarm on Gefran Inverter?
To resolve a DC link overvoltage alarm on your Gefran Inverter due to energy recovered from the motor, try extending the deceleration ramp. Alternatively, use a braking resistor connected to the appropriate terminals to dissipate the energy.
Why is my Gefran Inverter showing a DC link undervoltage alarm?
If your Gefran Inverter shows a DC link undervoltage alarm, the issue might be due to mains voltage being too low or overextended voltage drops, or poor cable connections. Check the connections and the mains voltage to resolve this.
What to do if my Gefran Inverter displays a heatsink temperature too high alarm?
To address a heatsink temperature too high alarm on your Gefran Inverter, verify the cooling fan is working correctly. Also, check that the heatsinks aren't clogged and that the openings for cabinet cooling air are not blocked.
How to troubleshoot instantaneous overcurrent alarm on Gefran Inverter?
If your Gefran Inverter displays an instantaneous overcurrent protection intervention alarm, it could be due to incorrect current regulator parameter settings or a short circuit. Check the current regulator parameters (menu 17) and inspect the wiring towards the motor.
What causes the Input air temperature too high alarm on a Gefran Inverter?
To resolve an Input air temperature too high alarm on your Gefran Inverter, check that the fan is operating correctly. Also, ensure the panel cooling air openings are unobstructed, and check the temperature inside the electrical panel.
What should I do if my Gefran Inverter displays an IGBT module temperature too high or too low alarm?
If your Gefran Inverter shows an IGBT module temperature alarm (too high or too low), verify the cooling fan's operation. Check that the heatsinks are not clogged and that the openings for the cabinet cooling air are not blocked.
Why does my Gefran Inverter show a motor overtemperature alarm?
If your Gefran Inverter is alarming due to a motor overtemperature, consider that the load cycle may be too heavy, the ambient temperature may be too high, or the motor's cooling fan may not be working. Change the processing cycle or use a cooling fan to cool the motor.
How to fix ground short circuit alarm on Gefran Inverter?
To address a ground short circuit alarm on your Gefran Inverter, check the drive and motor wiring. Also, verify that the motor is not grounded.
What does instantaneous overcurrent in IGBT bridge alarm mean on my Gefran Inverter?
If your Gefran Inverter is experiencing an instantaneous overcurrent in the IGBT bridge alarm, try switching the drive off and then on again. Check the condition of the braking resistor isolation, ensuring there are no earth leakages. If the alarm persists, it is recommended to contact the technical service center.
What to do if my Gefran Inverter displays a drive overload alarm?
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. Check that the load is not excessive and that the overload cycle is within allowed limits.
