to restart itself up to 10
times, it starts at 0 Hz
after auto restart
attempts.
- When the restart
counter reaches “11”
times, the operation
stops and the alarm
relay has the inactive
operation.

alarm relay has the
active operation.
- The VFD may
attempt to restart
itself continually, it
starts at 0 Hz after
auto restart attempts.
- After the 11 times
trip occurred, the
alarm relay has the
active operation and
then the VFD may
attempt to restart
itself.
