How to troubleshoot 'No supply voltage at the power section' on gefran AFE200?
- TtholderSep 9, 2025
If your Gefran Power Supply shows 'No supply voltage at the power section', check the drive power supply.
How to troubleshoot 'No supply voltage at the power section' on gefran AFE200?
If your Gefran Power Supply shows 'No supply voltage at the power section', check the drive power supply.
How to fix DC link overvoltage alarm on Gefran Power Supply?
If your Gefran Power Supply shows a DC link overvoltage alarm, it means the voltage supplied to the drive power section is too high. To resolve this, increase the bandwidth of the voltage regulator, especially if the issue arises under dynamic conditions.
What to do if Gefran Power Supply shows DC link undervoltage alarm?
If your Gefran Power Supply displays a DC link undervoltage alarm, it indicates that the voltage arriving at the drive power section is too low. You should check the connections and the mains voltage to resolve this issue.
How to resolve braking resistor overload alarm in gefran AFE200?
If you receive a 'Braking resistor overload alarm' on your Gefran Power Supply, it means the current absorbed by the resistor exceeds its rated capacity. To fix this, increase the Watt value of the braking resistor.
What causes ground fault alarm on gefran AFE200 and how to fix it?
If you are getting a 'Ground fault alarm' on your Gefran Power Supply, it indicates a ground short circuit. Check the wiring of the drive and the pre-load circuit to resolve this.
Why does my gefran AFE200 Power Supply show a heatsink temperature too high or too low alarm?
If your Gefran Power Supply shows a 'Heatsink temperature too high or too low alarm', it means the temperature has exceeded the set upper or lower limit for the linear temperature transducer. Verify the cooling fan is working correctly. Also, check that the heatsinks are not clogged and that the openings for cabinet cooling are not blocked.
What to do when Gefran Power Supply key is expiring?
Ask Gefran for the correct key to enable the desired firmware function.
How to resolve the error: 'The power card is configured for a drive that is incompatible with the regulation card' on gefran AFE200 Power Supply?
Download the correct configuration on the power card.
What to check if gefran AFE200 Power Supply shows drive overload alarm?
If the Gefran Power Supply displays a 'Drive overload alarm', check that the size of the drive is suitable for the application.
What should I do if my gefran AFE200 shows an emergency stop alarm?
If your Gefran Power Supply displays an 'Emergency stop alarm', eliminate the reason for which the Stop key on the keypad was pressed and reset the drive.
