• The motor is in a regenerative state
because the load causes the motor to run
at a frequency higher than the inverter
output frequency.
Inverter overload • The acceleration time ACC is too short.
• The DC braking amout is too large.
• The V/F setting is improper.
• A restart signal is input to the rotating
motor after a momentary stop, etc.
• The load is too large.
Motor overload • The V/F setting is improper.
• The motor is locked up.
• Low-speed operation is performed
continuously.
• An excessive load is applied to the motor
during operation.
Main module • The carrier frequency is high and load
overload
current has increased at low speeds
(mainly at 15Hz or less).
Over-torque trip • Over-torque reaches to a detection level
during operation.
Overheat • The cooling fan does not rotate.
• The ambient temperature is too high.
• The vent is blocked up.
• A heat generating device is installed close
to the inverter.
• The thermistor in the unit is broken.
Possible causes
• Insert a suitable input reactor.
