(Restart at
0Hz)
- The VFD may attempt to restart itself
up to 3 times it starts at 0 Hz after auto
restart attempts.
- When the restart counter reaches “4”
times, the operation stops and the
alarm relay has the active operation.
- The VFD may attempt to
restart itself up to 3 times it
starts at 0 Hz after auto
restart attempts.
- When the restart counter
reaches “4” times, the
operation stops.
- In case of all trips alarm
relay has the active
operation.
- The VFD may
attempt to restart
itself up to 3 times it
starts at 0 Hz after
auto restart attempts.
- When the restart
counter reaches “4”
times, the operation
stops and alarm
relay has active
operation.

(Resume
operation after
frequency
matching)
- The VFD may attempt to restart itself
up to 3 times in frequency matching
mode after auto restart attempts.
- When the restart counter reaches “4”
times, the operation stops and the
alarm relay has the active operation.
- The VFD may attempt to
restart itself up to 3 times it
starts in frequency
matching mode after auto
restart attempts.
- When the restart counter
reaches “4” times, the
operation stops.
