Problem Possible causes
• An external thermal trip is input.
• PTC protection worked.
• During automatic operation or remote
operation, a stop command is entered from
the operation panel or a remote input
device.
• A data writing error occurs.
• Power supply is cut off during 
operation and data writing is aborted.
• A data reading error occurred.
• The control RAM is defective.
• The control ROM is defective.
• The control CPU is defective.
• An error arises during serial communication. • Check the remote control device, cables,
• The current detector is defective.
• The error was occurred during Network
communication.
• The output current decreased to a low-
current detection level during operation.
• The input voltage (in the main circuit) is too
low.
• A ground fault occurs in the output cable or
the motor.
• Check the motor parameter  to .
• Check the base frequency  and the base frequency voltage .
• The motor with the capacity of 2 classes or less than the inverter is used.
• The output cable is too thin.
• The motor is rotating.
• The inverter is used for loads other than those of three-phase induction motors.
• Circuit board is changed.
(Or main circuit/drive circuit board)
• The signal input via VIA is below the analog
sinal detectio level set with .
• A communications error occurs between
control CPUs.
• The torque boost parameter  is set too
high.
• The torque boost parameter  is set too
high.
• The motor has too small impedance.
• The control CPU is defective.
• The motor shaft is locked.
• One output phase is open.
• An impact load is applied.

Remedies
• Check the external thermal input.
• Check the PTC in the motor.
• Reset the inverter.
• Turn off the inverter, then turn it again. If it
does not recover from the error, make a
service call.
• Turn the power off temporarily and turn it
back on, and then try  operation
again.
• Turn off the inverter, then turn it again. If it
does not recover from the error, make a
service call.
• Make a service call.
• Make a service call.
• Make a service call.
etc.
• Make a service call.
• Check the Network device and wiring.
• Enable  (low-current detection).
• Check the suitable detection level for the
system (, ).
• Make a service call if the setting is correct.
• Check the input voltage.
• Enable  (undervoltage trip
selection).
• To cope with a momentary stop due to
undervoltage, enable  (coast stop)
and  (auto-restart).
• Check the cable and the motor for ground
faults.
• Make a service call.
• Check the cables for breaks. And check
the setting of input signal or setting value
of .
• Make a service call.
• Re do the Auto-tuning then set .
• Re do the Auto-tuning then set .
• Decrease the setting of the torque boost
parameter , .
• Make a service call.
• Unlock the motor shaft.
• Check the interconnect cables between
the inverter and the motor.
