The Allen-Bradley 1746-HSRV SLC 500 Servo Control Module is designed for use with the 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 servo control module controls absolute position over a range of 32 bits, and 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 an encoder marker, limit switch, or limit switch and marker.
