What causes a motor overspeed alarm on a Gefran Inverter?
A motor overspeed alarm on your Gefran Inverter indicates that the motor speed exceeds the limits set in the PAR 4540 parameter. To fix this, limit the speed reference and check that the motor is not driven in overspeed during rotation.
What does a speed reference loss alarm mean on a gefran ADL550 Inverter?
A speed reference loss alarm on your Gefran Inverter means the difference between the speed regulator reference and the actual motor speed is more than 100 rpm, usually because the drive is in the current limit condition. Check that the load is not excessive.
What to check if my gefran ADL550 Inverter shows a power phase loss alarm?
If your Gefran Inverter displays a power phase loss alarm, check the mains voltage and whether any protections upstream of the drive have been tripped.
What should I do if my gefran ADL550 reports an output phase loss?
If your Gefran Inverter reports an output phase loss, check the drive/motor connection.
