Description

Product Overview

The Allen-Bradley 1771-HS3CR is a 3-axis servo controller module from the PLC 5 series (IMC-123). It installs in any 1771 I/O chassis and pairs with the 1771-PS7 power supply module rated at 120V AC and 1A. Weighing approximately 1.36 kg, this controller receives encoder and resolver feedback through a 50-pin I/O connector and delivers ±10V DC analog commands for precise multi-axis motion control.

Technical Configuration

The controller package includes a memory module, power module, encoder module, resolver, and optional hand-held pendant. It uses 96KB 1771-HM3A battery-backed memory cartridges to store AMP parameters and MML downloaded programs. The front-panel RS-232 port supports program upload/download and connects to T45 and T50 ODS via hand-held pendant for debugging. Encoder feedback is provided through an isolated 10V DC output with 250 kHz differential, single-ended input capability.

Installation Guide

Install the 1771-HS3CR in any compatible 1771 I/O chassis using 2 slots per ES. Connect the 1771-PS7 power supply through the 1771-CAS 9-pin connecting cable. Wire field connections using the 1771-WA wiring arm. Connect the 50-pin Axis E-stop I/O connector for encoder feedback, resolver signals, E-stop status, and fast I/O power. Use the RS-232 port for MML program upload/download or hand-held pendant debugging with T45 and T50 ODS.

Engineering Advantages

This controller delivers 3-axis motion control in a single module, reducing chassis slot requirements compared to separate single-axis controllers. The 250 kHz differential input supports high-resolution encoder feedback for precise positioning. Battery-backed 96KB memory cartridges preserve AMP parameters and MML programs through power loss. The 2 ms/axis update period enables responsive closed-loop control. c-UL, C-TICK, and CE certifications support global deployment.

Technical FAQs

Q1: How many axes does the 1771-HS3CR control?
A1: This module provides 3-axis servo control with ±10V DC analog command outputs and 2 ms/axis update period.

Q2: What power supply does this controller require?
A2: It uses the 1771-PS7 power supply module rated at 120V AC and 1A, connected via the 1771-CAS 9-pin cable.

Q3: What is the maximum encoder input frequency?
A3: The controller accepts up to 250 kHz differential input for encoder feedback signals.
