16. INDEXER POSITIONING OPERATION

16.8.2 JOG operation

(1) Setting
Set the devices and parameters as indicated below for the purpose of use. In this case, the next station
selection 1 to 8 (RYnA to RYnE and RY(n 2)3 to RY(n 2)5) and the speed selection 1 to 3 (RY(n 2)C
to RY(n 2)E) are invalid.

(2) Operation
Turn on the start (RYn1) to operate the servo motor with the servo motor speed set in the parameter
No.PC12, acceleration time constant and deceleration time constant set in the point table No.1. Turning off
RYn1 makes the servo motor decelerate to stop regardless of stations. For the rotation direction, refer to (2)
in section 16.8.1.
(3) Timing chart
The following timing chart shows an example when executing the 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.
