(1) The power supply has a capacity of
500kVA or more.
(2) A power factor improvement capacitor is
opened or closed.
(3) A system using a thyristor is connected
to the same power distribution line.
A restart signal is input to the rotating
motor after a momentary stop, etc.
Overvoltage during
The deceleration time is too short.
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.

Overvoltage during
The input voltage fluctuates abnormally.
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.
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).
Dynamic braking
The deceleration time is too short.
resistor overload trip
Dynamic braking is too large.
