Cause : Motor/inverter overload comes when the internal electronic thermal of the inverter determines the overheating of the motor. If the motor is overloaded the inverter turns off the output.

1. Motor has overheated.
2. Reduce load weight and operating duty.
3. Load is greater than inverter rating. ETH level is set too low.
4. Change inverter with higher capacity.
5. Inverter capacity is incorrectly selected. Inverter has been operated at low speed for too long.
6. Select correct inverter capacity.
