DMA 30A 7101-D

The Bosch Rexroth Indramat DMA 30A 7101-D from the DMA Servo Drive Modules series combines robust performance with flexible integration, delivering a 670 V input voltage capability and a stabilized 400 V output voltage for demanding three-phase applications. This DMA 30A 7101-D module supports a maximum current of 28 A and maintains a rated current of 18 A at 4 kHz switching frequency, while still delivering a rated current of 12 A at 8 kHz for high-speed control tasks. Engineered for synchronized speed, torque and position regulation, it features a cascade control structure with integrated position and speed controllers to streamline motion-management in complex systems. The compact footprint—521 mm height and 50 mm width—ensures efficient cabinet utilization without compromising on ventilation or service access.

At the heart of the design is a mains-friendly supply module with energy-recovery capability, paired with an integrated DC link connection that simplifies backplane integration. The module draws 1.23 A from a 24 VDC supply, making it easy to power auxiliary control circuits and safety I/O without additional power modules. High-speed communication is enabled by the SERCOS interface, which supports multiple drive modes, ultra-fast control-loop response, and simultaneous processing of setpoints and actual values. All critical parameters and commissioning data are stored in the module’s electronic nameplate, ensuring rapid replacement and minimal downtime.

Fully compatible with the Servodyn-D inverter system, the DMA 30A 7101-D snaps into the backplane for seamless plug-and-play operation and global deployment. Its digital closed-loop architecture excels in applications requiring precise positioning, wide speed ranges, and high dynamic response. Shipped with a one-year warranty from Wake Industrial, this module delivers industrial-grade reliability and simplifies integration into modern automation solutions.
