Description

The Allen-Bradley 1746-HSRV is a specialized single-axis servo control module engineered for the Allen-Bradley SLC 500 modular control system. This high-performance positioning module interfaces directly with SLC 5/03, 5/04, and 5/05 processors using RSLogix 500 programming software to execute complex motion control profiles independently of the programmable controller scan time. The module processes high-frequency encoder feedback and outputs pulse-train commands to drive external servo amplifiers or stepper drives with precise closed-loop or open-loop positioning.

Operationally, the 1746-HSRV manages absolute position tracking over a 32-bit range and supports advanced motion profiles including blended moves consisting of two to thirty-two sequential segments. Dedicated onboard microprocessors handle profile execution, homing (origin search) sequences utilizing encoder markers or limit switches, and real-time motion modifications without placing computational burdens on the main SLC backplane processor.

Features

  • Supports 32-bit absolute positioning over a wide range of motion profiles
  • Independent motion block execution asynchronous to SLC processor scan time
  • Blended motion profile execution supporting 2 to 32 linked move segments
  • High-frequency pulse input capability up to 300 kHz for accurate encoder feedback tracking
  • Comprehensive command modes including absolute, incremental, speed, monitor, hold, and emergency stop operations
  • Built-in origin search (homing) functionality with automatic position resetting via encoder marker or limit switches

Applications

  • Single-axis closed-loop positioning and motion control within SLC 500 automation racks
  • High-speed point-to-point material handling and linear slide positioning
  • Rotary indexing and coordinated multi-segment motion profiles
  • Retrofitting legacy step or servo motor drives in industrial manufacturing systems
