Description Possible causes
•Rapid acceleration is operated.
•The DC braking amount is too
large.
Inverter •The V/f setting is improper.
overload •A restart signal is input to the
rotating motor after a momentary
stop, etc.
•The load is too large.
•The V/f parameter is improperly
set.
•The motor is locked up.
Motor overload •Low-speed operation is performed
continuously.
•An excessive load is applied to the
motor during operation.
•Rapid deceleration is operated.

•The motor is in a regenerative
state because the load causes the
motor to run at a frequency higher
than the inverter output frequency.
