DM 30K 6311-D

The Bosch Rexroth Indramat DM 30K 6311-D from the DM Servo Drives series is a high-performance three-phase digital inverter module designed for demanding industrial applications. This standard variant of the Servodyn-D family operates on an input voltage of 670 V and features a native PROFIBUS-DP interface alongside a precision Resolver encoder for feedback. Engineered and manufactured by Bosch Rexroth Indramat, the DM 30K 6311-D delivers efficient motion control with robust build quality. Integration into automated systems is simplified by its slim chassis and well-documented interface protocols.

Air cooling ensures consistent thermal management, provided a minimum clearance of 100 mm around the module as recommended by the manufacturer. The device operates reliably across an ambient temperature range from 32 to 113 °F, with automatic current derating beyond the specified 30 A rated current to protect internal components. Both the regulated DC link voltage of 670 V and unregulated DC link voltage of 715 V accommodate dynamic load swings, while one-axis positioning functions are built in for single-motor drives. At 50 mm width and an approximate weight of 6 kg, the DM 30K 6311-D maximizes cabinet density without sacrificing serviceability.

Safety and longevity are assured by adherence to Bosch installation guidelines, including full de-energization before maintenance and compliance with local safety regulations. Inside a switch cabinet, the module’s thermal dissipation peaks at 156 W, and the 24 V DC control supply draws just 1.03 A, minimizing auxiliary power demands. A global one-year warranty backs the DM 30K 6311-D, ensuring rapid support and replacement in the event of manufacturing defects. This servo inverter represents a reliable, compact solution for OEMs and system integrators requiring precise, programmable motion control in industrial environments.
