(3) Status of positioning complete signal in selection of automatic servo OFF
Automatic servo OFF causes the actuator to be in other than the positioning complete state
due to the servo OFF. Positioning complete signal (PEND) is turned OFF. Changing the
PEND signal to the in-position signal judging whether the actuator is stopped within the
positioning width zone instead of the positioning complete signal allows PEND not to be
turned OFF during servo OFF.
This setting is reflected on complete position numbers PM1 to PM** in PIO patterns 0 to 3
and 6 confirming the positioning complete position No. or current position numbers PE* in
PIO patterns 4 and 7.
Define the setting in Parameter No.39.
