SLC Servo Module
Operation The SLC Servo Module, compatible with the SLC family, is used with
SLC 5/03 FRN 5.0 (and above) processors using RSLogix 500, AI500 or
APS (version 5.0 or higher) software. Once the SLC processor is
initiated, the execution of the motion block is independent of the scan
time of the processor. Blended motion allows for complicated move
profiles consisting of two to thirty-two segments. The blended move
profiles are stored in the SLC Servo Module’s memory as a series of
absolute moves and can be executed more than once. Other move or
homing operations can be performed between blended move profiles.
The SLC Servo Module controls absolute position over a range of 32
bits. The SLC Servo Module performs an origin search (also called
homing) and automatically resets the absolute position to the home
position when the SLC processor requests a search function after
detecting one of the following:
•
Encoder marker
•
Limit switch
