Panasonic rotary automatic door PS-A3600-2E shows the reason of frequency conversion trip.

Frequency conversion trip: it is not necessarily the fault of frequency converter. First, check whether the door is stuck. If the motor is overloaded, the inverter will trip. Then check whether there is any loose virtual connection in the motor wiring. If there is a loose virtual connection, a large current will be generated. If the current limit of the inverter is exceeded, the inverter will trip. Finally, check whether the rated current set by the inverter is consistent with the rated current of the motor. If there is nothing wrong, the frequency converter is broken. If the inverter is broken, find an aftermarket. Buying your own inverter is not much cheaper, and there is a warranty period after sale!
