DM 8K 7101-D

The DM 8K 7101-D drive from Bosch Rexroth Indramat is a member of the high-performance DM Servo Drives lineup, delivering robust motion control in a compact three-phase module. It features a 670V input stage and a built-in CANrho serial realtime communication interface for deterministic data exchange. A standardized encoder interface (Standard encoder) ensures compatibility with a wide range of Rexroth motor variants, including SF synchronous and asynchronous machines. This module dovetails seamlessly with the Servodyn-D inverter series to provide precise speed and position control in demanding automation applications.

Designed for precision and efficiency, the DM 8K 7101-D offers 12-bit resolution on its actual position feedback and sustains a 10 A maximum current at carrier frequencies up to 8 kHz, with a 1.1 A rated current in continuous operation. At a 4 kHz modulation frequency, it delivers a 2.1 A rated current, while retaining the same peak capacity. The auxiliary 24 V power supply delivers 0.89 A to control logic, and the power stage limits losses to 96.5 W under full load. On the DC side, a robust busbar DC link connection supports up to 35 A of output current, and an internal/external ballast switch offers flexible energy dissipation options.

Engineered for reliability, the DM 8K 7101-D incorporates redundant safety channels and electronic rating plates for automated commissioning, minimizing downtime and commissioning errors. Its standardized form factor and common interface simplify integration into existing Servodyn-D installations or new multi-axis platforms. Ideal for high-precision positioning, synchronization tasks, and dynamic motion control in packaging, printing, and metalworking industries, this module combines proven Rexroth quality with versatile performance.
