DMA 45A 3301-D

The DMA 45A 3301-D, Bosch Rexroth Indramat, DMA Servo Drive Modules marks a precision three-phase drive module within Rexroth’s Servodyn-D family. This compact unit delivers advanced motion control with integrated smart controllers handling speed, position, and torque regulation seamlessly. It bridges the gap between high-performance servo motors and machine-level automation, enabling real-time adjustments under demanding industrial loads. Rugged design principles ensure that it withstands electrical noise and maintains consistent performance over long service intervals.

Key specifications include a 24 VDC current input of 1.32 A, an Input Voltage rating of 670 V, and an Output Voltage of 400 V, giving a robust DC-to-three-phase conversion. The module’s Width of 50 mm allows installation in densely populated control racks, while the Integrated DC link connection simplifies bus topology and reduces wiring complexity. Communication is provided via a Serial Realtime Communication Interface, ensuring deterministic data exchange between drives and controllers. Data integrity is protected by optical waveguides, which fully shield against electromagnetic interference, and backplane modules enable plug-in mounting and tool-free replacement.

Engineers appreciate how the DMA 45A 3301-D integrates directly into Rexroth’s Servodyn-D ecosystem, streamlining commissioning and firmware updates. Its compact dimensions and modular backplane architecture accelerate installation and maintenance tasks in both new and retrofit systems. The combination of reliable power conversion, low-noise communication, and global warranty support ensures uptime and productivity across a wide range of high-precision motion applications.
