-2 tools (select 1 and 3) For example, if you command the indexer to move from tool 4 to
tool 2,you will see the select 1 and 3 lights come on
briefly.
-3 tools (select 3)
don’t move (nothing active)
this means no commands were sent, therefore no lights
come on.
The following table reflects the description above:

PLC Outputs
There are 6 outputs from the PLC to the 4-tool indexer.
Q1 = Motor on - fwd direction
This light will be on when the indexer motor is
running forward
Q2 = Motor on - rev direction
This light will be on when the indexer motor is
running reverse
See the table below for the bit patterns for corresponding tools.
Q3 = Bit #1
Q4 = Bit #2
Q5 = Bit #3
Q6 = Bit #4
Q1 & Q2 goes to the motor driver PCB
Q3 - Q6 goes to the control - identifies position feedback to control
The following table reflects the meaning of the bit signals back to the control. Keep in
mind that the 4-tool indexer reports back up to 4 absolute positions to the PLC and the
PLC will output up to 8 absolute positions back to the control.

You can verify the bit pattern below by getting a voltmeter and seeing if a 5 volt signal is
present when a bit reads 1 in the above table. For example, if the indexer is physically
on tool 3, bits 1 and 2 should read 5 volts and bits 3 and 4 should read 0 volts. This
procedure is best done when checking the inputs 1 through 4 above with the outputs.
To measure a bit with your voltmeter you will need to do the following. For example, for
bit 1, place you meter across Q3 on the PLC and a ground point.

Motor Driver Settings
Please see the following drawing for an illustration of how the pots are to be adjusted on
the motor driver board in the cable breakout box. The flat part of the pot should be in
the location shown in the figure. Customer service may require a visual inspection of
these settings. Also, please verify the position of 2 switches on the motor drive board.
CAUTION!
Do not adjust any of these settings. This may cause the indexer to not run correctly or not run
at all and will void the warranty of the hardware.
