PRODUCT INFORMATION
Product Overview
The Allen-Bradley 1746-HSRV is an SLC 500 single-axis closed-loop servo control module. It interfaces directly with five-volt or fifteen-volt encoder systems. The unit tracks encoder feedback up to 300 kilohertz for precise positioning. Block execution operates independently of chassis processor scan time. The module provides an analog velocity command range up to plus or minus 10 volts DC. Position control uses an internal 32-bit register structure. Front-panel status LEDs assist technicians during diagnostic evaluations.
This single-slot module functions within standard SLC 500 chassis architectures. It supports SLC 5/03, SLC 5/04, and SLC 5/05 processors. Systems accommodate up to 12 modules per chassis for multi-axis servo applications. Operating modes include configuration mode and active command mode. The module utilizes class 3 communications with up to 12 input words and 12 output words. Parameters transfer through M-file data structures during system configuration.
