Isolated Inputs: Accepts Floating or Grounded Signals of 0‑10VDC or 4‑20mA for Controlling the Speed of the Motor. Burr‑Brown Isolation Provides .01% Linearity
Speed Range and Regulation: 1% Regulation Over 60:1 Speed Range. 0.1% Regulation Over 80:1 Speed Range with the Addition of a Tachometer for Feedback
User Adjustable Calibration Pots: IR Compensation, Min Speed (12 Turn), Max Speed (12 Turn), Current Limit, Acceleration, Deceleration and Tachometer
Diagnostic LEDs: LEDs for Power, Run (MM501U Only) and Current Limit Status
Stopping Modes: Start/Stop Circuitry for Three Wire Remote Pushbuttons or Two Wire Maintained Switches
The MM500 Series of dual‑voltage single quadrant SCR drives can control 90 or 180 VDC SCR brush‑type motors ranging from 1/20 HP through 5 HP. The MM501U drive has integrated isolation allowing it to precisely follow analog current or voltage signals from external devices or a potentiometer as a reference for motor speed control. This results in significant labor and material cost reduction compared to other systems employing a separate drive and isolation card.
Use the MM500 Series for a full featured, high end, great performing single quadrant DC drive.
Cage Clamp Terminal Block: Quick and Easy Wire Terminations Reduce Installation Time
Additional Features: Tachometer Feedback Mode and On Board Fusing
