The Bosch Rexroth Indramat DMD02.1-W042N is a digital servo drive controller from the DMD Servo Drives series. It features a continuous output current of 2.5 Arms, operates at a nominal voltage of 230 V in 1- or 3-phase configurations, and supports a rated output of 400 W. The drive uses natural cooling and includes a dynamic brake function, with encoder feedback resolution of 2500 pulses per revolution.
Internal Product Review
The DMD02.1-W042N is a digital servo drive controller with a 400 W rated output. IGBT PWM sine-wave driving and natural cooling give the drive smooth control characteristics and clean cabinet integration. A very capable choice for precise servo applications.

Product Description:
The DMD02.1-W042N digital servo drive controller is produced by Bosch Rexroth Indramat under the DMD Servo Drives series. Installed between a motion processor and a synchronous motor, it converts high-level commands into regulated phase current so that industrial axes reach the requested position, speed, or torque. An integrated RS232C service interface allows direct parameter loading and diagnostic access from a laptop. This cabinet-mounted unit is suited for closed-loop automation tasks on assembly lines, pick-and-place robots, and light machining centers.
The drive operates from a single-phase or three-phase 200 to 230 V supply range, with a nominal input of 3 x AC 230 V. Under rated conditions, it draws 1.8 A and delivers 2.5 Arms to the motor, with a rated output of 400 W. Current is modulated by an IGBT PWM method that supports a small-signal bandwidth of at least 300 Hz and helps maintain a smooth output waveform. Motion commands use a 31-bit signed position word, and the velocity command range scales to 500 kpps. The incremental feedback channel accepts a 2,500-pulse encoder over ten wires, overspeed protection limits shaft speed to 6,000 rpm, momentary acceleration current reaches 10.5 A peak, the unit uses natural convection cooling, it is Design 1, it belongs to Line 2, and a 17.82 J DC bus capacitor stores energy for short supply interruptions.
Protective logic trips at 20 A of phase current, opens at 400 VDC on the bus, and responds at 190 VDC when supply sag is detected. During braking, the converter channels 7 W continuously and up to 1600 W in bursts into the regenerative resistor, while the dynamic brake switch provides immediate dissipation. Move profiles are scheduled in 10 ms increments to match the 5-bit position I/O handshake used by external sequence contacts. The enclosure tolerates vibration up to 4.9 m/s² and ambient humidity up to 90% RH, while natural convection keeps internal temperature within operating limits without fans.
