How to fix Drive overload [DOL] on Gefran Inverter?
A 'Drive overload' alarm on a Gefran Inverter means that the inverter output current has exceeded the allowed overload value, or the overload cycle has exceeded the allowed values. Check that the load and accelerations are not excessive, and ensure that the overload cycle is within the allowed limits.
What does MultiUndervolt [MUV] mean in Gefran Inverter?
The 'MultiUndervolt' alarm on your Gefran Inverter indicates that there have been too many Undervoltage alarms. To fix this, use the suggested solutions for the Undervoltage alarm.
What does MultiDesat [MDES] mean in Gefran Inverter?
The 'MultiDesat' alarm on your Gefran Inverter indicates that there have been too many Desaturation alarms. You should implement the solutions proposed for the Desaturation alarm.
What does MultiOvercurr [MOC] mean in Gefran Inverter?
The 'MultiOvercurr' alarm on your Gefran Inverter means that there have been too many Overcurrent alarms. To resolve this, implement the solutions provided for the Overcurrent alarm.
What does Ground fault [GNDF] mean on a Gefran Inverter?
A 'Ground fault' alarm on a Gefran Inverter indicates a ground short circuit. Check the drive and motor wiring, and ensure the motor is not grounded.
Why does Gefran Inverter show Motor OT [MOT] alarm?
The Gefran Inverter displays a motor overtemperature alarm for several potential reasons: - The load cycle might be too heavy. - The motor could be installed in a location with a high ambient temperature. - If the motor has a blower, the fan might not be functioning. - If the motor lacks a blower, the load may be too high at slow speeds, where the cooling fan on the motor shaft isn't sufficient. - The motor might be operating at less than its rated frequency, resulting in increased magnetic losses. To resolve this, consider changing the processing cycle or using a cooling fan to cool the motor.
What to do if Gefran Inverter shows Undervoltage [UV]?
If your Gefran Inverter is displaying an undervoltage alarm, it signifies that the voltage arriving at the drive power section is too low compared to the minimum threshold related to the Mains voltage parameter setting. This can occur if the mains voltage is too low or due to overextended voltage drops. Poor cable connections, such as loose contactor terminals, inductance, or filters, can also cause this issue. You should check the connections and mains voltage.
What causes Heatsink OT [HOT] alarm on Gefran Inverter?
The 'Heatsink OT' alarm on your Gefran Inverter indicates that the heatsink temperature is too high. This could be due to several reasons: - The cooling fan may not be working correctly. - The heatsinks might be clogged. - The openings for the cabinet cooling air could be blocked. Verify the correct operation of the cooling fan, check for any blockages in the heatsinks, and ensure that the cabinet cooling air openings are not obstructed.
What to do if Gefran Inverter displays Overcurrent [OC]?
If your Gefran Inverter is showing an overcurrent alarm, it means the instantaneous overcurrent protection has been triggered. This could be due to incorrect settings of the current regulator parameters or a short circuit between phases or a ground fault on the drive output. Check the current regulator parameters and inspect the wiring to the motor.
