Allen-Bradley 1746-HSRV SLC Servo Control Module

Allen-Bradley 1746-HSRV Servo Control Module is a single-axis, closed-loop servo controller for the SLC 500 family. It operates with SLC 500 processors, executing motion control via ladder logic and storing motion profiles in internal memory for absolute moves, blends, and repeats; it can reset absolute position when an encoder marker pulse is detected. The module accepts encoder feedback up to 300 kHz (0° quadrature error) for precise position and velocity control, and draws 300 mA from the 5 V backplane. It provides 3 general-purpose local fast inputs and 1 general-purpose local fast output for signaling and interfacing with the drive system. In addition, it supports an analog velocity command input with programmable limits up to ±10 V DC to drive compatible Rockwell servo drives. The 1746-HSRV is compatible with a variety of SLC 500 processors and its motion logic can run independent of the processor scan time to maintain deterministic motion performance.
