EVO 150 Controller 47
Appendix 9 / PLC I/O Board
The PLC I/O board allows the EVO 150 system to be remotely controlled by the customer's PLC.
There are eight control inputs (SERVO-CENTER, EDGE A, EDGE B, LINE / CENTERLINE,
MANUAL, IN, OUT, and AUXILIARY) and five status outputs (IN LIMIT, OUT LIMIT, SERVO-
CENTER LIMIT, AUTO MODE, and NO FAULT). All inputs and outputs are opto-isolated.
Warning: It is the responsibility of the customer to insure machine safety. Changing the
mode of operation from any source (front-panel switchpad or PLC I/O inputs) can cause
machine motion.
Note: All PLC I/O board inputs are opto-isolated, including the AUXILIARY input. If your
application requires a
non-isolated
AUXILIARY input, then set parameter 72 to 1. Refer to
page 21 for more information about setting controller parameters.
