What to do if Gefran Inverter displays Speed feedback loss alarm?
If the Gefran Inverter displays a Speed feedback loss alarm, see parameter 2172 SpdFbkLoss code for information about the cause of the alarm and chapter 10.2 Speed fbk loss [22] alarm.
What to do if gefran ADP200 Inverter shows Overcurrent [OC] alarm?
If your Gefran Inverter displays an instantaneous overcurrent protection intervention alarm, this might be due to incorrect current regulator parameter settings. To resolve this: - Check the current regulator parameters (menu 17). - Check the wiring towards the motor.
Why gefran ADP200 shows DC link undervoltage alarm?
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).
What causes motor overload alarm on Gefran Inverter?
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.
How to resolve parameter database error on Gefran Inverter?
If an error occurs during the enabling of the parameter database saved in the Flash memory and one parameter value is out of range, and code XXXXH indicates the number of the parameter (Hex) that has caused the error when the database is enabled, set the parameter causing the error to a value within the range and run Save parameter. Switch the drive off and then switch it back on again.
What to do if gefran ADP200 Inverter shows Encoder error [ENCE]?
Take the recommended action for the Speed fbk loss alarm.
What to do if Gefran Inverter exceeds the number of automatic restarts after Desaturation alarm?
If your Gefran Inverter shows that the number of attempted automatic restarts after the Desaturation alarm was exceeded, adopt the proposed solutions for the Desaturation alarm, because there are too many Desaturation alarms.
How to reset Emergency stop alarm on Gefran Inverter?
Eliminate the reason for which the Stop key on the keypad was pressed and reset the Gefran Inverter.
What to do if Gefran Inverter detects optional card issue?
If the user has removed the card on purpose, execute Save parameters. If the user has not removed the card, identify and replace the faulty card.
How to resolve intake air temperature too high alarm on Gefran Inverter?
If the Gefran Inverter displays an intake air temperature too high alarm, check correct fan operation.
