Problem
The deceleration time is too short.
Overvoltage during
deceleration
(Regenerative energy is too large.)
Overvoltage limit operation is set
to 1. (Disabled).
The input voltage fluctuates abnormally.
(1) The power supply has a capacity of
500kVA or more.
(2) A power factor improvement capacitor is
opened and closed.
(3) A system using a thyristor is connected
to the same power distribution line.
The input voltage fluctuates abnormally.
Overvoltage during
constant-speed
(1) The power supply has a capacity of
operation
500kVA or more.
(2) A power factor improvement capacitor is
opened or closed.
(3) A system using a thyrister is connected
to the same power distribution line.
The motor is in a regenerative state
because the load causes the motor to run
at a frequency higher than the inverter
output frequency.
The acceleration time ACC is too short.
Inverter overload
The DC braking amount 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.
The V/F setting is improper.
Motor overload
The motor is locked up.
Low-speed operation is performed
continuously.
An excessive load is applied to the motor
during operation.
The carrier frequency is high and load

current has increased at low speeds
(mainly at 15Hz or less).
The deceleration time is too short.
Dynamic braking
Dynamic braking is too large.

Power running torque reached f441 or
more and maintain in f452 during
power running.
