Problem
Overcurrent during • The acceleration time  is too short.
acceleration
• The V/F setting is improper.
• A restart signal is imput to the rotating
motor after a momentary stop, etc.
• A special motor (e.g. motor with a small
impedance) is used.
Overcurrent during • The deceleration time  is too short.
deceleration
Overcurrent during • The load fluctuates abruptly.
constant speed • The load is in an abnormal condition.
operation
Overcurrent (An • The insulation of the output main circuit or
overcurrent on the
motor is defective.
load side at start-up)
• The motor has too small impedance.
Arm overcurrent at • A main circuit elements is defective.
start-up
Input phase failure • A phase failure occured in the input line of
the main circuit.
• The capacitor in the main circuit lacks
capacitance.
Output phase failure • A phase failure occurred in the output line
of the main circuit.
Possible causes
• Increase the acceleration time .
• Check the V/F parameter.
• Use  (auto-restart) and 
• Adjust the carrier frequency .
• Set the carrier frequency control mode
• Increase the deceleration time .
• Set the carrier frequency control mode
• Reduce the load fluctuation.
• Check the load (operated machine).
• Set the carrier frequency control mode
• Check the cables and wires for defective
• Make a service call.
• Check the main circuit input line for phase
• Enable  (input phase failure
• Check the capacitor in the main circuit for
