DM 8K 6111-D

DM 8K 6111-D, Bosch Rexroth Indramat, Servodyn-D: The DM 8K 6111-D servo drive from Bosch Rexroth Indramat is a high-performance member of the Servodyn-D series, engineered for demanding motion control applications. This three-phase module integrates seamlessly with synchronous SF and SR motors, as well as standard or asynchronous DU series motors, delivering precise positioning in a compact form factor. Its native PROFIBUS-DP and Sercos communication interfaces ensure deterministic data exchange, while an onboard resolver yields 12-bit resolution for ultra-fine position feedback. Rugged design and optimized thermal characteristics make it ideal for dense control cabinets.

In terms of technical attributes, the drive accepts a nominal Input Voltage: 670 V and draws 0.89 A from a 24 V supply for its control electronics. Its power loss is rated at only 96.5 W, minimizing heat dissipation in enclosed racks. The module’s width of 50 mm and mass of 6 kg support compact system layouts and simplified handling. Communication is secured over optical waveguides to eliminate EMI effects, and a robust DC link connection via busbars supports regenerative braking. The integrated start-up circuit and external ballast switch afford safe commissioning and energy dumping. Housed in an IP20-class enclosure, it reliably operates up to 45 °C ambient temperature.

Engineers benefit from the DM 8K 6111-D’s modular build and standardized encoder interface for rapid on-site swaps and firmware cloning. Its dual-interface approach—combining PROFIBUS-DP for legacy lines and Sercos for high-speed topologies—provides installation flexibility and future-proof scalability. With global shipping and a one-year warranty, this drive delivers dependable performance and ease of integration across diverse industrial automation installations.
