minimum frequency.
The [STOP/RESET] key is pressed. Check that the stoppage is
normal, if so resume operation
normally.
Motor torque is too low. Change the operation modes
(V/F, IM, and Sensorless). If 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.
The motor is overheating. The load is too heavy. 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
apllications with inverters.
Connect the AC reactor to the
inverter output (set the carrier
frequency to 2 kHz).
The motor fan has stopped or the
fan is obstructed with debris. Check the motor fan and remove
