12. WHEN USING WITH A GENERAL-PURPOSE INTERFACE
12 - 60
(c) Automatic operation timing chart
1) Automatic individual positioning operation
a) Absolute value command method ([Pr. PT01] = _ _ _ 0)
While the servo motor is stopped under servo-on state, switching on ST1 (Forward rotation
start) starts the automatic positioning operation.
The following shows the timing chart.

(Note 1)
Note 1. The detection of external input signals is delayed only by the time set in the input filter setting of [Pr. PD29].
Considering the output signal sequence from the controller and change in signal variations due to hardware,
configure a sequence that changes the point table selection earlier.
2. Up to four points of DO are available; therefore, PT0 to PT7 cannot be outputted simultaneously.
3. M code can be read with M code actual value (2D6Ah).
