Product Description
The Allen-Bradley 1746-HSTP1 is a single-slot stepper controller module for SLC 500 series processors, offering precise stepper motor control with encoder feedback for position verification (not closed-loop control). It supports differential encoders (+5 or +15V) and provides a 250 kHz pulse train output for micro-stepping, handling up to 8,000,000 absolute position counts. The module features programmable operation (no DIP switches), loopback diagnostics, LED indicators for status, and interfaces with various translators and opto-couplers. It operates within a temperature range of 0-60C and can be used in larger PLC systems via the 1746-ASB module. Its dimensions are approximately 5" x 2" x 6" (13 cm x 5 cm x 15 cm) and it weighs around 15 oz (0.43 kg).
Is Your Device Showing These Signs?
The Allen Bradley 1746-HSTP1 module commonly experiences issues such as communication failures due to corrupted backplane connectivity or faulty DH+ network configuration. Resolve these issues by verifying the PLC's power supply, inspecting the DH+ cabling for shorts or opens, and confirming proper termination resistance. Address program logic errors that prevent data transfer and ensure the correct node address is assigned to the 1746-HSTP1 within the DH+ network. Replace the module if hardware diagnostics indicate internal component failure, such as a damaged transceiver or memory corruption, after exhausting all other troubleshooting steps.

Our Repair Process for the
1746-HSTP1
Our repair process for the Allen Bradley 1746-HSTP1 module begins with a verification of the PLC's power supply and a thorough inspection of the DH+ cabling for any shorts or opens; proper termination resistance is confirmed. Program logic errors that impede data transfer are addressed, and the correct node address is assigned to the 1746-HSTP1 within the DH+ network. If these steps do not resolve the issue, hardware diagnostics are performed to identify internal component failures, such as a damaged transceiver or memory corruption. Module replacement occurs only after all other troubleshooting steps have been exhausted and hardware diagnostics confirm irreparable internal damage.
