When the output current of the AC drive is
within the range of [F8-42 (detection level of
current 1)±F8-43 (detection width of current
1)] x F1-03 (rated motor current), the DO
terminal outputs an active signal.

4.5.2 FWD/REV Switchover Dead-zone Time
FWD/REV switchover dead-zone time (F8-13) indicates the transition time at 0 Hz output during
transition between forward running and reverse running of the AC drive.
