(1) Setting of periods taken until automatic servo OFF
Three periods from completion of positioning to automatic servo OFF can be set in the
following parameters in seconds [sec].
Parameter No.

No.38) and then automatically turning servo OFF
(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 also reflected to the complete position numbers PM1 to PM** of PIO patterns 0
to 3 in PIO converter or the current position number PE** of PIO pattern 4 in positioner mode
2, which are to check the positioning complete position number.
Define the setting in Parameter No.39.
