What to do if Panasonic VF0 400V class Inverter motor doesn't rotate and fault display is lit?
If the motor does not rotate and the fault display is lit, it indicates an inverter malfunction. Contact Matsushita for assistance.
What to do if my Panasonic VF0 400V class Inverter says motor has over temperature?
If the Panasonic Inverter indicates the motor has an over temperature, first, consider reducing the load factor. If the motor is overloaded, increasing the motor capacity may also help; if the motor capacity then exceeds the inverter capacity, increase the inverter capacity accordingly. Reducing V/F characteristics, reducing the motor load factor, or ensuring correct operation at low frequency could also resolve the issue. If the problem persists, the inverter may be malfunctioning, and you should contact Matsushita.
