Maintenance Operations
The motor rotates even after Inverter output is stopped.
When the motor starts, an overcurrent fault (E02) is detected and the motor stalls.
Problem
Probable cause
Correction
The motor rotates even
after Inverter output is
stopped.
If the motor continues operating at
low speed, without completely
stopping, even after a decelera-
tion stop has been executed, it
means that the DC injection brak-
ing is not decelerating enough.
Increase the parameter in P05 for DC injection
braking-to-stop time or increase the decelera-
tion time.
Problem
Probable cause
Correction
When the motor starts,
an overcurrent fault
(E02) is detected and
the motor stalls.
DC injection braking is insufficient
at startup. This can also occur if
the motor is already turning when
the motor is started.
This can be prevented by slowing the rotation
of the motor by DC injection braking before
starting the motor. Increase the parameter in
P04 for startup DC injection braking time.
