DMA 140D 3301-D

DMA 140D 3301-D, Bosch Rexroth Indramat, DMA Servo Drive Modules represents a fully digital three-phase drive module engineered for seamless integration into the Servodyn-D inverter backplane. This module supports both brushless synchronous and induction motor control, delivering modular flexibility for complex machine designs. Manufactured to exacting industry standards, it shares its architecture with the Servodyn-D Series of servo and asynchronous motor drives. Its compact profile and robust digital control suit industrial motion applications where precision and uptime are critical.

Boasting a suite of precision features, the DMA 140D 3301-D accepts an Input Voltage 670V three-phase supply and provides a regulated Output Voltage 400V for downstream power stages. The module’s 24 VDC current input 1.58 A powers internal logic, while an air cooling (backplane mechanics) system maintains optimal thermal conditions without auxiliary fans. An analog interface with a 16-bit resolution ensures high-fidelity command and feedback signals, complemented by a resolver encoder interface for accurate rotor position detection. The drive’s electrical stage supports a 140 kHz maximum current switching frequency, and its mechanical housing spans 200 mm width to fit standard Servodyn-D rack assemblies.

Engineered for plug-and-play integration, the DMA 140D 3301-D module simplifies system expansion on the Servodyn-D bus, reducing commissioning time and wiring complexity. Its fully digital control algorithms and VeCon processor chip deliver dependable speed, position, and current regulation under varying load conditions. Whether deployed in synchronous, asynchronous, or linear motor configurations, this drive module provides a reliable foundation for high-performance automation systems.
