The Allen-Bradley 1746-HSTP1 is a high-speed stepper controller module designed for the SLC 500 programmable controller platform. This single-axis module provides precise open-loop motion control for stepper motor applications. It generates a pulse train output (PTO) to command a stepper drive, enabling accurate control over position, speed, and acceleration. The module is ideal for applications requiring simple yet effective point-to-point positioning, such as indexing tables, conveyors, and material handling systems. It integrates seamlessly into any available I/O slot in an SLC 500 chassis and is configured using RSLogix 500 software, simplifying setup and programming.
