DM 30K 5111-D

The DM 30K 5111-D servo drive is produced by Bosch Rexroth Indramat as part of the DM Servo Drives series. It converts the regulated DC power of a common bus into phase-controlled output for a single servo motor, enabling precision position and speed control in automated assembly cells and conveyor zones. The unit also supplies feedback power and monitors motor conditions, making it a key component wherever closed-loop motion is required in plants.

Its power stage maintains a regulated DC link of 670 VDC, which serves as the energy reservoir for the pulse-width-modulated output. Control electronics draw 1.03 A from an external 24 V service supply, allowing logic functions to remain energized during main power isolation. Thermal removal relies on air cooling, so cabinet airflow must be verified to match the switching frequency selected. At 4 kHz carrier frequency the continuous output is 5.8 Arms, while selecting 8 kHz reduces the rating to 3.6 Arms because of higher switching losses. These losses manifest as heat that tops out at 156 W under nominal load, a figure used when sizing enclosure ventilation and drive mounting plates.

For short acceleration bursts the module can supply 29 Arms at a 4 kHz carrier, but output margin decreases linearly above 45 °C. The specified derating slope of 0.35 A/K helps engineers calculate safe current limits when the ambient reaches the 55 °C ceiling. With a shipping mass of 6.0 kg, the drive can be installed on standard DIN rails or bolted heat sinks without excessive load on panel hardware, ensuring mechanical integrity while maintaining the electrical capabilities detailed above. This servo drive can be shipped internationally and Wake Industrial provides a one year warranty on this DM 30K 5111-D servo drive.
