level.
The load is too high. Operate the motor independently.
An emergency stop signal is input. Reset the emergency stop signal.
The wiring for the control circuit terminal
is incorrect. Check the wiring for the control circuit
terminal.
The input option for the frequency
command is incorrect. Check the input option for the
frequency command.
The input voltage or current for the
frequency command is incorrect. Check the input voltage or current for
the frequency command.
The PNP/NPN mode is selected
incorrectly.
Check the PNP/NPN mode setting.
The frequency command value is too
low.
Check the frequency command and
input a value above the minimum
frequency.
The [OFF] key is pressed.
Check that the stop state is normal, if
so resume operation normally.
Motor torque is too low.
Increase the volume of the torque
boost. 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 The load is too heavy. Reduce the load.
