DMA 140D 1103-D, Bosch Rexroth Indramat, DMA Servo Drive Modules.

The DMA 140D 1103-D from Bosch Rexroth Indramat is part of the advanced DMA Servo Drive Modules series. This three-phase inverter module combines digital power electronics with backplane mechanics for seamless insertion into Servodyn-D system racks. With a compact 200 mm module width and robust air-cooling assembly, it maintains optimal temperatures under continuous operation. Engineered for both synchronous and asynchronous motors, it supports high-dynamics drive applications.

Core specifications include an Input Voltage of 670 V, delivering a regulated Output Voltage of 400 V to downstream power stages. The module’s 24 VDC current input of 1.58 A powers control logic and onboard sensors. A high-speed 32-bit signal processor and native SERCOS interface ensure deterministic control with fibre-optic linking between adjacent modules. A standard encoder interface provides precise feedback, while the air-cooling system with integrated backplane mechanics guarantees continuous operation up to maximum switching rates of 140 kHz. Modules are interconnected via fiber optics, offering galvanic isolation and real-time data exchange. All units ship with a 12-month warranty for global deployment.

Integration into Rexroth’s Servodyn-D multi-axis architectures is straightforward thanks to plug-in backplane guides and standardized interfaces. The proven air-cooling and sealed power electronics underpin reliable performance in harsh industrial environments. Ideal for packaging lines, robotics, and high-speed machine tools, the DMA 140D 1103-D delivers precise motion control, rapid commissioning, and high uptime.
