Product Description:

The DMD02.1-W022N digital servo drive controller is produced by Bosch Rexroth Indramat and belongs to the DMD Servo Drives series. It accepts single-phase or three-phase 200–230 V power and uses an IGBT PWM sine-wave method to excite connected motors. By coordinating encoder feedback with programmable motion points, the unit provides closed-loop control for axes in pick-and-place modules, material-handling gantries, and similar automated equipment. This control approach lets the drive correct position and speed as load conditions change during repetitive motion. Its natural cooling design allows cabinet integration without auxiliary fans.

Under rated load, the drive supplies a continuous armature current of 1.6 Arms, enough to sustain a mechanical output of 200 W on the connected axis. Acceleration and deceleration intervals can be tuned in increments of 10 ms, allowing precise cycle conditioning in indexing stations. For transient demands, the power stage tolerates a peak current of 6.9 Ao-p, while an electronic cutoff at 20 A prevents semiconductor damage during faults. That combination supports steady torque production in normal operation and brief current headroom during starts and load spikes. The controller’s regeneration circuit handles 5 W continuously so braking energy does not raise the DC link voltage during routine stopping. RS-232C connectivity passes parameter data and motion commands directly from supervisory controllers.

Overspeed detection trips if feedback reaches 6000 r/min, ensuring that mechanical limits are not exceeded during tuning errors or load loss. During abrupt deceleration events, the internal resistor can absorb a maximum of 1600 W of regenerated power without external braking hardware. The motion card communicates absolute target values through a 31-bit signed position word, and incremental encoder feedback is processed at up to 500 kpps so positional data remains synchronous with high-speed command sequences. The unit also uses 400 VDC overvoltage and 190 VDC undervoltage thresholds to maintain stable operation. This helps protect the power stage during supply dips and regenerated voltage rise.
