NSK Megatorque PS Series - Outputs of Operating Conditions

— 8-17 —
 The output closes when the Motor position data is in the set zone.
◊ When the Motor passes the zone with high speed or when the zone is too narrow, the
zone passage time gets short. The parameter ZAW (Zone passage stability timer) is
available to set the minimum time width for detecting the passage.
