Product Description:

The DMD01.1-W022N digital servo drive controller is produced by Bosch Rexroth Indramat as part of the DMD Servo Drives series. It powers and regulates a matched servomotor in compact automation stations, converting AC mains energy into controlled three-phase output while exchanging position data with a supervisory PLC. The unit maintains precise speed, torque, and position on machinery used for assembly, inspection, or light material-handling tasks. This arrangement supports compact machine layouts where controlled axis motion must remain repeatable.

Its electrical input accepts a single-phase or three-phase supply with a tolerance of +10%/-15% at 50 or 60 Hz, and the internal bus is referenced to a nominal 3 x AC 230 V. The drive communicates with the host through an RS-232C port, while an incremental encoder with 2,500 pulses per revolution returns position data. Continuous current output is 1.6 Arms, with a momentary peak of 6.9 Ao-p, and output switching is handled by the IGBT PWM sine-wave driving method. A separate logic supply of 24 V powers the control electronics. When motor and load inertias match, the frequency response is 300 Hz or more, and the rated mechanical output is 200 W. The continuous input current on a three-phase line is 1.1 A.

Energy returned during deceleration is dissipated by an internal resistor that handles 5 W continuously and up to 1600 W in short bursts, while stored DC-bus energy is 8.91 J. An available dynamic brake is supported, and protective thresholds are set as follows: overcurrent is limited at 20 A, overvoltage trips at 400 VDC, undervoltage stops operation below 190 VDC, and overspeed protection disconnects the drive at 6000 rpm. The chassis uses natural cooling, so free airflow is required around the 50 mm wide, 130 mm deep, and 168 mm high frame. The line and design are both set to 1.
