11.3 Troubleshooting Other Faults
When a fault other than those identified as faults or warnings occurs, refer to the following table for
possible causes and remedies.
Type
Cause
Remedy
Parameters
cannot be set.
The inverter is in operation (driving
mode).
Stop the inverter to change to
program mode and set the parameter.
The parameter access is incorrect.
Check the correct parameter access
level and set the parameter.
The password is incorrect.
Check the password, disable the
parameter lock and set the parameter.
Low voltage is detected.
Check the power input to resolve the
low voltage and set the parameter.
The motor does
not rotate.
The frequency command source is set
incorrectly.
Check the frequency command
source setting.
The operation command source is set
incorrectly.
Check the operation command
source setting.
Power is not supplied to the terminal
R/S/T.
Check the terminal connections
R/S/T and U/V/W.
The charge lamp is turned off.
Turn on the inverter.
The operation command is off.
Turn on the operation command.
(RUN).
The motor is locked.
Unlock the motor or lower the load
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] button is pressed.
Check that the stop state is normal, if
so resume operation normally.
Motor torque is too low.
Increase the amount 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
Check the forward/reverse rotation
wiring.
