16. INDEXER POSITIONING OPERATION
(3) Operation
Turn on the start (RYn1) to operate the servo motor with the servo motor speed, acceleration time constant,
and deceleration time constant set in the point table No.1. Turning off RYn1 makes the servo motor
execute positioning to the station where the servo motor can decelerate to stop. For the rotation direction,
refer to (2) in this section.
(4) Timing chart
The following timing chart shows an example when executing the indexer JOG operation from the status
where the servo motor is at a stop on the station No.0 when the servo-on is turned on.
