Allen Bradley 1771-HS3A 3-Axis Servo Controller
The Allen Bradley 1771-HS3A is a specialized 3-axis servo controller housed within the legacy 1771 I/O chassis, extending the capabilities of the IMC 120 series. This module combines multi-axis motion logic with a modular hardware footprint for industrial automation applications.
Memory & Power Configuration
Data persistence for downloaded MML programs and AMP parameter sets is maintained through the 1771-HMA 96 KB battery-backed memory cartridge, ensuring operational logic retention through power cycles. System power is supplied via a 1771-PS7 module capable of handling 120-240V AC at 1A/2A, which interfaces with the controller's power port through a ruggedized 9-pin 1771-CAS cable assembly.
Feedback & Signal Processing
The 1771-HS3A accommodates both resolver and encoder feedback systems, providing high-resolution positioning data for precise closed-loop servo control. When utilizing resolver feedback, the module's excitation circuit generates precise Sine and Cosine signals to activate the stator. The encoder interface supports 10V DC isolated outputs alongside 250 KHz differential and 20 KHz single-ended inputs.
Commissioning & Control Interface
Field commissioning and real-time variable overrides are facilitated through the onboard RS-232 port, enabling connection to T45 or T50 Operating Data Stations (ODS). Technicians can leverage optional Hand-Held pendants for localized tuning and system optimization.
