Product Description:

The DMA 08A 4101-D is a drive module from Bosch Rexroth Indramat in the DMA Servo Drive Modules series. Designed as a three-phase inverter for synchronous and asynchronous motors, it supplies controlled power and regenerative braking to motion axes in automated machinery during acceleration, speed regulation, and deceleration. Mounted in a modular rack, the unit ties into a common DC bus and exchanges diagnostic data with higher-level controllers, creating a compact motion node for material handling lines, packaging cells, and similar equipment.

The housing occupies a frontal width of 50 mm, so multiple axes can be installed side by side without exceeding standard cabinet rails in high-density layouts. Thermal energy is removed by backplane air cooling; the airflow drawn across the rear heat sink permits dense stacking while keeping semiconductor junctions within their rated range. Command values enter through an analog interface with 16-bit resolution, enabling fine torque or speed reference steps that match the accuracy of modern PLC analog output cards. For position feedback, the module expects a standard encoder interface, which simplifies motor selection because compatible resolver, incremental, or SSI encoders using the common wiring scheme can be connected directly. The unit has no plug-in option cards, so it ships without installed auxiliary blocks.

Functionally, the device is a three-phase module for synchronous and asynchronous motors. This topology lets one inverter serve both permanent-magnet and induction machines, allowing mixed-motor installations to use the same drive platform across different axis types. The controller firmware is identified as the Servodyn-D series, confirming compatibility with companion supply modules and diagnostic software in that family. Hardware marking shows the standard variant, so protective conformal coatings, special bus couplers, and marine approvals are not included.
