SPS-2722 Servo Digital Controls for Commercial Applications
Overview
The Servo Digital Control Unit (SDC) is a microprocessor-based, servo controller, providing both position and rate-loop control of the positioner.A firmware download that modifies digital compensation filters allows the position and rate servo-loops to be optimized for different payloads.The SDC includes multiple RS-422/RS-232/RS-485 and Ethernet ports to allow control of, and access to, the signals generated by sensors and monitoring equipment associated with the payload. Honeywell's brushless, low-torque-ripple motors and the Pulse-Width-Modulated (PWM) amplifiers within the SDC provide rapid and precise control of the pedestal.The SDC monitors servo faults and provides a number of safety features, which include the ability to prevent remote operation of the positioner while maintenance personnel are working on the unit.The SDC is available for mounting in either a 19-inch EIA rack, a NEMA weatherproof enclosure or it can be custom packaged. The SDC may be commanded by an external computer system, joystick, or autotracker.
