Why is my Gefran Power Supply showing an instantaneous overcurrent alarm?
An instantaneous overcurrent alarm in the Gefran Power Supply might occur due to incorrect phase settings or a ground fault on the drive output. Check the wiring to the mains, ensuring the phases match those of the synchronization card. Also, verify the current regulator parameters.
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 if gefran AFE200 shows Instantaneous overcurrent alarm?
If your Gefran Power Supply is showing 'Instantaneous overcurrent alarm', switch the drive off and then on again. If the alarm persists, contact technical support.
What does 'External alarm present' mean on my gefran AFE200?
If your Gefran Power Supply displays an 'External alarm present' message, it means a digital input programmed as an external alarm does not have the +24V voltage available on the terminal. Check that the terminal screws are tight.
How do I fix an intake air temperature too high alarm on a Gefran Power Supply?
If your Gefran Power Supply displays an 'Intake air temperature too high alarm', check that the cooling fan is operating correctly.
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.
