Product Overview

The 1771-HS3CR is a 3-axis servo controller from Allen-Bradley. It belongs to the PLC 5 series. This module fits any 1771 I/O chassis. It uses a 1771-PS7 power supply. The controller manages three servo axes. It receives encoder and resolver feedback. It also handles E-stop signals. The front panel has an RS-232 port. This port allows program upload and download. You can connect a hand-held pendant. The pendant helps debug MML programs. The module has 120V AC fuse voltage. The input frequency is 250 kHz differential. Output is +/-10V DC analog command. It occupies 2 slots per ES module. Update period is 2 ms per axis. Backplane current is 1.7 Amperes. The wiring arm is 1771-WA. Pulse capture time is 50-9.999 microseconds. Dimensions are 3.5 x 6.5 x 2.0 inches. It weighs about 1.36 kg.

Application Scenarios
