The DCS920 PWM servo drive is designed to drive brush type DC motors at a high switching frequency. The drive can interface with digital controllers or be used stand-alone and requires only a single unregulated DC power supply. Input (Ref) gain, Tach Gain, Loop gain, Integrator Frequency and Offset can be adjusted using 26-turn potentiometers. The offset adjusting potentiometer can also be used as an on-board input signal for testing purposes. Furthermore, 3 red/green LEDs indicate operating status for faster setup. The drive is fully protected against over-voltage, under voltage, over-current, short-circuits from output to output, and over-temperature.


  • Separate and adjustable current Limits: Continuous, Peak and Peak-time
  • No integrator windup when disabled
  • Current Monitor Output
  • 3 LED Indicators for Faster Setup:Normal/Enable, Power-OK, Fault (Short-circuits or over temperature)
  • Over/Under-voltage, over-current, short-circuits, over temperature protection
