DM 4K 5111-D

The Bosch Rexroth Indramat DM 4K 5111-D from the DM Servo Drives series is a high-precision three-phase current module designed for seamless integration in industrial automation systems. As part of the Servodyn-D family, it features a Standard Encoder interface, Input Voltage: 670V, and a 24 V Control Signal interface for reliable command and feedback. This compact unit incorporates a regulated DC link voltage of 670 VDC and is optimized for use with asynchronous and synchronous motors via Bosch Rexroth’s prefabricated cabling and connectors. The module’s robust design mandates installation within an IP54 protective cabinet equipped with air filters to maintain contamination-free cooling.

Engineering excellence is evident in its thermal management and mechanical footprint. The drive sustains a maximum operating temperature of 45 °C at rated load and up to 55 °C under derated conditions, relying on an efficient air-cooling system to dissipate heat. It supports motors with a frame size of 90 and power ratings from 0.25 kW to 1.5 kW, delivering precise one-axis positioning. With a lightweight mass of 6.0 kg and a narrow 50 mm width, the module accommodates a two-row arrangement to maximize cabinet density while preserving service access.

Commissioning is streamlined through the DSS programming environment, enabling fast parameter setup and diagnostic checks. A plug-in point-to-point protective circuit terminal and fiber-optic link on the left side enhance functional safety and signal integrity. The unit ships globally via a dedicated delivery service and carries a one-year warranty, reflecting Bosch Rexroth Indramat’s commitment to durability and worldwide support.
