Allen-Bradley 1746-HSTP1 | SLC 500 Stepper Controller Module

Product Overview

The Allen-Bradley 1746-HSTP1 is a single-axis Stepper Controller Module for the SLC 500 platform. It delivers high-speed stepper motor control with speeds from 1 to 250,000 pulses per second. This module is ideal for precision motion control in robotics, conveyors, and CNC machines.

Core Functionality

The 1746-HSTP1 controls one stepper motor via an external driver. It features trapezoidal velocity profiling with acceleration ranges from 1 to 2000 pulses per second² and rapid step rate adjustment under 4ms. Differential inputs ensure signal accuracy, while digital outputs control motor operation. The module integrates with SLC 500 via 1746-HT or 1746-HCA I/O connections.

Technical Specifications

Installation Guide

Install the 1746-HSTP1 in any available SLC 500 chassis slot. Connect the stepper motor driver to the module via 1746-HT or 1746-HCA I/O modules. Wire differential inputs for position feedback and digital outputs for motor control. Configure motion parameters (speed, acceleration, step rate) in the SLC 500 program.

Engineering Advantages

This module delivers high-speed stepper control up to 250kHz with precise acceleration profiles. The trapezoidal velocity curve ensures smooth motion. Fast 4ms step rate adjustment enables responsive control. Differential inputs reject noise for reliable position feedback. Ideal for single-axis motion control in packaging, material handling, and CNC applications.
