16. INDEXER POSITIONING OPERATION
POINT
To execute the indexer positioning operation, parameter needs to be
changed. Set the parameter No.PA01 to "1 ".
The indexer positioning operation is available with servo amplifiers with
software version A6 or later.
This chapter provides the indexer positioning operation method using MR-J3- T servo amplifier. Any matters
not described in this chapter are the same as those of the point table positioning operation. For more
information, refer to chapters up to 15.
16.1 Function
16.1.1 Overview
Using the next station selection 1 (RYnA) to the next station selection 8 (RY(n 2)5) devices, stations from
No.0 to No.254 can be specified.
Settings of servo motor speed and acceleration/deceleration time constant are carried out by specifying the
point table number from 1 to 8 using the speed selection 1 (RY(n 2)C) to the speed selection 3 (RY(n 2)E)
devices. Speed command data can be directly specified by using the remote register when two stations are
occupied.

Rotation direction
specifying indexer
Positioning operation is executed to the set station. Rotation direction can be specified.
Shortest rotating
indexer Positioning operation is executed to the set station. The servo motor rotates in the closest
direction from current position.

Indexer JOG
operation
Turning on the start signal (RYn1) makes the servo motor rotate in the direction specified by
the rotation direction specifying.
Turning off the start signal (RYn1) makes the servo motor perform positioning operation to the
closest station where the motor can decelerate to stop.
JOG operation
Executes an inching operation with the CC-Link communication based on speed data set with
parameters.
