DMA 140D 4101-D

DMA 140D 4101-D, Bosch Rexroth Indramat, DMA Servo Drive Modules The DMA 140D 4101-D three-phase drive module from Bosch Rexroth Indramat’s DMA Servo Drive Modules series supports both synchronous and asynchronous motors. It belongs to the Servodyn-D inverter family, featuring a modular structure of axis and supply modules, offering direct power connection and digital closed-loop control of current, speed, and position. The drive integrates seamlessly with SF and SR series synchronous motors, DU type and standard asynchronous motors, as well as linear and built-in motors with defined encoders. Air-cooled via backplane mechanics, the module is optimized for demanding industrial servo applications.

Paragraph Two: The module operates with a regulated 670 V DC and an unregulated 715 V DC DC-link voltage, delivering a rated current of 42 A and a maximum current of 141 A for peak performance. Thermal management includes a defined derating of 2.25 A/°C over the 45 … 55 °C ambient range, while an integrated air-cooling scheme ensures long-term stability. Auxiliary power requirements are minimal, drawing only 1.58 A from the 24 V DC supply module. The compact footprint measures 200 mm in width and 521 mm in height, and the module accommodates a 16-bit analog interface alongside a standard encoder interface and an onboard RS-232 port for parameter configuration.

Paragraph Three: The DMA 140D 4101-D excels in modular installations, enabling fast swapping of axis modules with pre-loaded parameters via PC connection, thus minimizing downtime. Its rugged design and precise closed-loop algorithms enhance reliability across high-duty servo and automation systems. Ideal for global deployment, the drive arrives with a comprehensive one-year warranty and delivers consistent, high-precision motion control in complex machinery environments.
