Product Description:

The DMA 15A 1101-D is a servo drive module in the DMA Servo Drive Modules series from Bosch Rexroth Indramat. Designed for multi-axis racks, it is a power stage that converts DC bus energy into controlled AC output for synchronous and asynchronous motors used in industrial automation. By adjusting motor current in real time, the module enables closed-loop speed, torque, and position control in machine tools, printing lines, and assembly equipment. This makes it suitable for automation cells that require several compact axes to operate from one shared drive platform.

The unit uses backplane air cooling, meaning airflow along the rear mounting plane removes heat so no internal fan is required. Its feedback channel is provided through a standard interface, making it compatible with common incremental or absolute encoders without custom adapters. For motion-bus communication, the drive supports the deterministic SERCOS interface, which transfers setpoints and status words over fiber with very low latency. Cabinet width impact is minimized by a 50 mm housing profile, allowing dense side-by-side placement of multiple axes and helping preserve rack space. Functionally, it is a three-phase module that can energize both synchronous and asynchronous motors, which supports mixed motor selections on the same power rail.

The drive belongs to the Servodyn-D series and is released as the Standard Variant. It has no additional functions such as integrated safety or expanded digital I/O, so its role stays focused on base motion control. That arrangement suits cabinets where separate safety hardware or external I/O modules handle those tasks. The module uses standardized connectors for system wiring, which helps keep rack integration straightforward across matching modules. Rear ventilation clearance still needs to be maintained so the cooling path along the mounting plane can work as intended.
