the fault remains, replace the inverter with a model with
increased capacity.
The motor rotates in the opposite direction to the command.
The wiring for the motor output cable is
incorrect.
Determine if the cable on the output side is wired
correctly to the phase (U/V/W) of the motor.
The signal connection between the control
circuit terminal (forward/reverse rotation) of
the inverter and the forward/reverse rotation
signal on the control panel side is incorrect.
Check the forward/reverse rotation wiring.
The motor only rotates in one direction.
Reverse rotation prevention is selected.
Remove the reverse rotation prevention.
The reverse rotation signal is not provided,
even when a 3-wire sequence is selected.
Check the input signal associated with the 3-wire
operation and adjust as necessary.
Reduce the load.
Increase the Acc/Dec time.
Check the motor parameters and set the correct values.
Replace the motor and the inverter with models with
appropriate capacity for the load.
The ambient temperature of the motor is too
high.
Lower the ambient temperature of the motor.
The phase-to-phase voltage of the motor is
insufficient.
Use a motor that can withstand phase-to-phase
voltages surges greater than the maximum surge
voltage.
Only use motors suitable for apllicatiosn with inverters.
Connect the AC reactor to the inverter output (set the
carrier frequency to 2 kHz in H39).
The motor fan has stopped or the fan is
obstructed with debris.
Check the motor fan and remove any foreign objects.
