Product Overview

The INDEXER Module is a single-axis positioning device that is equipped with a program table operation
function. The INDEXER Module is mounted to the side of the SERVOPACK.
The INDEXER Module has two reference methods: digital I/O and serial commands.
Digital I/O is structured as a program table (Mode 0) or homing/JOG speed table (Mode 1). If the program
table (Mode 0) is being used, the program step selected with the input signal pattern (binary format) can be
executed. If the JOG speed table (Mode 1) is being used, the JOG speed selected with the input signal pattern
(binary format) can be executed.
With serial commands, ASCII command strings are sent to the INDEXER Module through RS-422 or RS-485
communications and these commands are interpreted and executed immediately.
The support software tool, SigmaWin+, can be used to easily set program tables and parameters or to perform
monitoring operations.
These same operations can also be performed using serial commands.

Function
The program step selection input signals (binary format) are used to select the desired
positioning data from the program table stored in the INDEXER Module. The
INDEXER Module can store up to 256 program steps. The program steps can be
linked to create combinations that perform more complex motions.
Homing using an incremental encoder and operation using a JOG speed table with up
to 16 speed levels can be performed.
Positioning can be controlled by ASCII command strings received through RS-422
or RS-485 communications. Up to 16 axes can be connected. ASCII commands can
also be used to operate using a program table.
Both the program table and serial commands are equipped with registration functions
for external positioning.
There are 8 output signals (/POUT0 to /POUT7) for which the output status can be
specified.
The programmable output signals (/POUT0 to /POUT4) can also be used as zone sig-
nals. Up to 32 zones can be specified in the zone table.
