DMA 45A 1301-D

The Bosch Rexroth Indramat DMA 45A 1301-D is a high-performance module in the DMA Servo Drive Modules series, designed to provide precise motion control in demanding industrial environments. This DMA 45A 1301-D unit operates on a three-phase supply with an input voltage of 670 V and delivers an output voltage of 400 V for efficient drive performance. Bosch Rexroth Indramat integrates a 24 VDC current input of 1.32 A to power its internal logic and interface circuits, ensuring stable operation under variable loads. Engineered for modularity, the DMA 45A 1301-D features a backplane connector that allows direct plug-in installation and simplifies system expansion.

The DMA 45A 1301-D supports a rated current of 10 A at 4 kHz switching frequency for short-time overloads and sustains a continuous current of 23 A, with a peak current capability of 39 A for demanding dynamic loads. Its closed-loop architecture communicates via the Sercos interface, offering compatibility with sine encoders, incremental encoders, and cosine encoders for submicron position feedback. The drive’s control loops execute at cycle times of 125 µs for speed, 250 µs for current, and 500 µs for position, delivering high responsiveness to command inputs. Optical waveguide connections provide enhanced interference immunity, making the unit resilient against electromagnetic disturbances common in industrial settings.

Compact yet robust, the DMA 45A 1301-D module integrates seamlessly into the Servodyn-D platform, enabling the construction of high dynamic motion control systems tailored to synchronous and asynchronous motor applications. Its modular design and global one-year warranty support from Bosch Rexroth Indramat make it an ideal choice for machine builders seeking reliable, precision drive solutions in packaging, robotics, and material handling sectors.
