Product Description:

The DMD01.1-W042N is a digital servo drive controller manufactured by Bosch Rexroth Indramat for the DMD Servo Drives series. Installed between a motion controller and a servo motor, it converts line power into regulated three-phase output while processing high-resolution feedback. This closed-loop action lets automated packaging machines, assembly stations, and pick-and-place gantries hold commanded velocity and stop points. It is intended for industrial motion systems that require stable speed regulation and repeatable stopping accuracy. The wall-mountable housing suits electrical cabinets where heat must be dissipated without fans, and the control electronics coordinate drive, brake, and diagnostic functions for continuous plant duty.

Its control core uses the IGBT PWM Method (Sine-wave driving) to produce low-ripple phase currents, and status data can be queried over a RS232C link for parameter setting. The serial connection provides access to operating data during local setup and status checks. The input range supports 1-phase or 3-phase operation at 200 to 230 V and 50/60 Hz, and the continuous input current is 1.8 A. Under rated conditions, the drive delivers up to 2.5 Arms to the motor. A dynamic brake function absorbs regenerated energy during rapid deceleration. Motor position is read by an incremental encoder (2,500 P/r), allowing a frequency response of at least 300 Hz when the motor and load inertias are matched. Heat is removed through natural cooling, so no external blower is required. Nominal output voltage equals the three-phase 230 V line, and overcurrent protection trips at 20 A to protect the IGBT bridge.

For short transients, the inverter can source 10.5 Ao-p, giving extra torque during brief acceleration or deceleration events. Power capability is rated at 400 W, and overspeed protection halts output if rotor speed exceeds 6000 r/min. Overvoltage shutdown activates at 400 VDC, while undervoltage monitoring asserts at 190 VDC to help prevent control loss. The unit is design 1 and line 1, and its frequency characteristics support stable response across the specified load range.
