PRODUCT INFORMATION
Product Overview
The Allen-Bradley 1746-HSTP1 is a single-slot stepper controller module designed for the SLC 500 platform. It provides single-axis stepper motor control with motion feedback verification for industrial positioning applications. The unit connects directly to stepper motor drivers across a broad pulse velocity range. It interfaces with differential incremental encoders operating at either 5V DC or 15V DC. System configuration is handled entirely through user programming without manual DIP switches.
This intelligent controller operates with SLC 5/01 through SLC 5/05 processors and fixed chassis units. It can also integrate into broader architecture via the 1746-ASB remote I/O adapter module. Backplane current draw is rated at 200 mA at 5V DC and 90 mA at 24V DC. Built-in loopback diagnostics actively track pulse train commands delivered to the translator. Diagnostic status LEDs indicate normal operation, programming errors, and faulted states during runtime.
