Product Description:
The DMA 45A 7101-D is a servo drive module produced by Bosch Rexroth Indramat and supplied within the DMA Servo Drive Modules series. It is intended to energize and regulate three-phase synchronous or asynchronous motors in automated lines where compact drive axes share a common DC bus. The module operates as an intermediate amplifier between the plant controller and the motor, translating drive commands into controlled current and voltage profiles for precise torque and speed regulation. In coordinated motion systems, this arrangement lets the axis respond quickly to changing speed and load demands while remaining integrated with the higher-level control architecture.
Mechanical layout is fixed at 50 mm width, allowing high-density stacking on the backplane. Heat generated by the power electronics is removed by backplane air cooling, so cabinet airflow must reach the finned rear panel. Feedback signals are accepted through a standard interface, simplifying connection to motor-mounted encoders without proprietary adapters. Fieldbus communication is available through CANrho, giving cyclic data exchange for command and diagnostic telegrams. The logic board has no additional functions. Classified as a 3-phase module for synchronous and asynchronous motors, the unit supplies controlled AC output phases derived from the shared DC link for both motor types.
The configuration shipped here corresponds to the standard variant, meaning it follows the baseline design without special extensions. Within the wider drive platform, it carries the identifier Servodyn-D series, which matches supply modules, braking choppers, and communication accessories that use the same platform designation. Production is handled by Bosch Rexroth Indramat. Its format suits cabinets that distribute power centrally and place several amplifier modules side by side, which helps keep wiring short between the DC bus, control electronics, and connected motors. This arrangement supports compact multi-axis layouts in transfer systems, handling equipment, and other automated machinery that rely on synchronized motor control.
