DMA 45A 6311-D

DMA 45A 6311-D, Bosch Rexroth Indramat, DMA Servo Drive Modules deliver robust three-phase inverter performance within the Servodyn-D Series. This module integrates seamlessly with synchronously controlled SR, SF, and linear motors as well as asynchronous DU and standard types, providing coordinated position, velocity, acceleration, and deceleration management via a native PROFIBUS-DP interface. The onboard VeCon chip processes real-time feedback to maintain precise motor control, while dual fans and forced convection cooling ensure consistent thermal regulation. Designed to generate a stabilized 670/715 VDC link for the inverter and supply ancillary electronics, this drive module is the heart of high-performance motion systems.

In detailed operation, the DMA 45A 6311-D draws 1.32 A at 24 VDC for control circuitry and accepts a three-phase Input Voltage 670V bus to produce an Output Voltage 400V output for the motor inverter. Its 12-bit resolver encoder interface supports fine resolution feedback, and a selectable 4 kHz/8 kHz switching frequency accommodates both precision positioning and dynamic response. The unit dissipates 220 W under full load and operates reliably across an ambient temperature range from 0 to +45 °C, safeguarded by an IP20 enclosure rating. Compact at 521 mm in height and 50 mm in width, the module plugs directly into the Servodyn-D backplane, minimizing cabinet footprint while preserving service access.

Engineers value the DMA 45A 6311-D for its straightforward integration into Rexroth's modular inverter topology, enabling rapid expansion from single-axis drives to multi-axis motion platforms. Its proven reliability under continuous duty and comprehensive protection standards deliver low downtime and consistent throughput in packaging, material handling, and industrial automation applications. With Wake Industrial's one-year global warranty, the DMA drive assures long-term performance and support in demanding production environments.
