Digital Servo Drive

The SXD 15 digital servo drive from Allied Motion (Amherst, NY) is a compact, modular unit that can drive a DC brush, DC brushless, or AC brushless motor requiring up to 1 kW of power. It can be either panel- or DIN-- rail mounted, and features standard ratings of 12 to 80 VDC bus, 15 A continuous, and 30 A peak current. Additional features include torque, velocity, and position control modes; four digital inputs, one digital output, all isolated, and two analog inputs plus one analog output; communication via RS232, RS485, or CAN; a Keep-Alive feature to enable maintaining logic power with the main power off; and protection against short circuits, voltage excursions, and temperature extremes.
