DMA 140D 1201-D

DMA 140D 1201-D, Bosch Rexroth Indramat, DMA Servo Drive Modules opens as a fully digital three-phase module designed for integration into the Servodyn-D inverter ecosystem. The module leverages a compact backplane format with robust air cooling system and precision backplane mechanics to maintain optimal thermal regulation under continuous operation. Tailored for brushless asynchronous and synchronous motor control, it inherits the proven architecture of IGBT output stages to ensure high efficiency and low noise. Built for seamless rack-based deployment, this drive module supports advanced position control and SERCOS communication at its core.

Incorporating a nominal Input Voltage 670V and delivering a stabilized Output Voltage 400V, the DMA 140D 1201-D manages a 24 VDC current input 1.58 A for its control electronics. It achieves a peak switching performance up to 140 kHz while occupying a slim 200 mm module width, conserving valuable rack space. The embedded 32-bit resolution processor board executes motion algorithms with ultra-low latency and interfaces via SERCOS fiber optics to realize full digital control of position, current, and speed loops. Encoder feedback is handled by a dedicated gear encoder channel within the SERCOS interface, guaranteeing precise rotor position tracking across all operating points.

Designed to pair seamlessly with asynchronous and built-in motors featuring gear or absolute encoders, the DMA 140D 1201-D enhances system reliability through its modular, hot-swappable format. Its standardized backplane connectivity and universal firmware platform simplify maintenance and scale-out across diverse axis counts. With global shipping support and a one-year warranty, this module delivers proven Rexroth Indramat quality for high-performance motion applications in machine tools, packaging systems, and automated assembly lines.
