DM 8K 5111-D

The Bosch Rexroth Indramat DM 8K 5111-D from the DM Servo Drives series integrates seamlessly into high-performance motion control systems with a 670V input voltage and a 24 V Control Signal interface. This three-phase Servodyn-D module is engineered for precise operation with a Standard encoder and a 12-bit resolver for high-resolution position feedback. Featuring a compact frame of 430 mm height and 50 mm width, the unit mounts easily in dense drive cabinets. Proprietary backplane connectivity ensures a robust, redundant safety structure with two-channel monitoring for fault-tolerant performance.

The DM 8K 5111-D delivers up to 35 A peak output current on its DC link connection via busbars and supports dual overload profiles at both 4 kHz and 8 kHz switching frequencies. At 4 kHz, it furnishes a 10 A max current and 2.1 A rated current under overload, while at 8 kHz these values shift to 10 A max and 1.1 A rated. An integrated start-up circuit, external and internal ballast switches, and cold-module engineering backplane modules optimize power handling and simplify serviceability. The state-of-the-art Serial Realtime Communication System ring interface of optical fibers processes both setpoints and actual values in a single cycle, minimizing latency in closed-loop control.

Designed for global deployment, the DM 8K 5111-D carries a one-year warranty and ships ready for installation in demanding drive environments. Its modular architecture, combined with precise speed and position regulation, makes it ideal for servo motors across industrial automation applications. With integrated safety, high-density packaging, and versatile communication options, this drive module delivers pinpoint accuracy and reliable operation in synchronized multi-axis systems.
