Product Description:

Bosch Rexroth Indramat’s DM 30K 9101-D is a servo drive module in the DM Servo Drives series. It converts a rectified DC bus into finely modulated three-phase outputs that synchronize with feedback signals, providing closed-loop motion control for conveyors, robotic joints, and packaging lines. The module’s compact mechanical layout minimizes panel depth and simplifies wiring, which helps increase axis density without enlarging the enclosure. This operating approach supports repeatable speed regulation and positioning in automated production equipment.

The drive operates from a DC link held at 670 VDC / 715 VDC, enabling enough headroom for regenerative braking and high-speed positioning. Air cooling draws cabinet air across the heat sink, so no external liquid circuit is required. In closed-loop mode at 4 kHz, the continuous output reaches 14 A rms, while at 8 kHz it sustains 9.7 A rms; these values indicate the long-term thermal load on connected motors. When an application demands rapid acceleration, the unit can deliver open-loop surges of 29 A rms at 4 kHz or 22 A rms at 8 kHz without triggering current foldback. Command data arrive through a CAN bus setpoint interface that supports CANopen and CANrho profiles, linking the drive directly to PLC networks.

The anodized aluminum housing stands 430 mm tall and 50 mm wide, yet it weighs 6.0 kg, allowing high-density stacking on DIN rails. Internal losses are limited to 156 W, which simplifies cabinet ventilation calculations when multiple axes share the same bay. Control power is supplied from a 24 V auxiliary rail, where the drive draws just 1.03 A during normal operation. Position feedback is accepted through either an STG or MTG encoder interface, giving 20-bit resolution for STG transducers and 32-bit resolution for MTG devices, which supports fine interpolation and smooth velocity loops. The availability of both encoder options gives the drive flexibility when paired with different motor feedback arrangements.
