Product Summary
The Allen-Bradley 1771-HS3CR provides high-speed, three-axis servo control for your PLC 5 system. It accepts feedback from encoders and resolvers to deliver precise positioning. This module also stores critical AMP parameters and MML programs on a battery-backed memory cartridge.
Product Procurement & Buyer Guide
The 1771-HS3CR controls three independent servo axes with one compact module. This design significantly reduces the required chassis slots. You also avoid the cost of three separate single-axis controllers. This module operates on a standard 120 Volts AC supply. It draws a backplane current of 1.7 Amperes. Ensure your 1771-PS7 power supply can meet this current demand. The controller processes encoder feedback at a maximum of 250 Kilohertz. This high frequency allows for very high-resolution motion control. Use the 1771-CAS connecting cable to link the module to its power supply. The system uses the 96KB 1771-HM3A battery-backed memory cartridge. This cartridge retains all your programs and parameters after a power loss. The module provides analogue command outputs of +/- 10 Volt DC. This standard signal level interfaces with most modern servo drives. Buy this module to add complex motion profiling to your legacy PLC 5 system. It delivers proven reliability for multi-axis packaging, assembly, and material handling applications.
Step-by-Step User & Installation Guide
First, mount the 1771-HS3CR in any available slot within your 1771 I/O chassis. The module occupies two slots per ES module. Use the provided 1771-WA wiring arm for all field wiring connections. Connect the 1771-PS7 power supply using the 1771-CAS 9-pin cable. This provides the required 120 Volts AC and 1 Amp power. Next, establish encoder feedback by wiring to the 250 KHz differential input. The controller also accepts single-ended encoder signals. Connect your resolver feedback to the dedicated pins on the 50-pin I/O connector. This same connector handles E-stop status and E-stop start signals. Use it to provide fast I/O power to external devices. Then, connect an RS-232 cable to the front panel port. You use this port to upload or download MML programs to the memory module. You can also connect a T45 or T50 handheld pendant here. This pendant helps you debug MML programs and hardware. Configure the module's update period to 2 ms per axis. The pulse capture time ranges from 50 to 9.999 microseconds for precise timing.
