Product Description:

The DMA 30A 5111-D is a drive module in the DMA Servo Drive Modules series from Bosch Rexroth Indramat. Mounted in a Servodyn rack, it functions as a three-phase power stage that supplies and regulates current for synchronous or asynchronous motors used in material transport, pick-and-place systems, and indexing mechanisms. It interfaces with higher-level motion control so a single mechanical axis can follow commanded speed and position values during repetitive machine cycles. The unit is intended for distributed automation cells that require compact axis control inside a shared rack system.

A width of 50 mm supports dense rack layouts where multiple axes must fit into limited cabinet space. Heat is removed by backplane air cooling, which draws thermal energy through the rear bus rail and avoids the need for separate fan assemblies at the module face. Motor feedback is connected through the standard interface, allowing the module to read incremental or absolute encoder signals without option cards. The power section is a three-phase module for synchronous and asynchronous motors, and it operates from the AC link voltage supplied by a common power unit. The internal control also supports single-axis positioning, so commanded target positions can be processed directly for stand-alone moves.

The logic terminals accept 24 V control signals, matching the nominal level used by typical PLC I/O. In multi-axis racks, the module is part of the Servodyn-D series, and the backplane supports coordinated drive numbering and fault handling across adjacent axes in the same rack. This unit is supplied as the standard variant, so it uses the baseline feature set without optional safety or high-speed encoder additions. Status indication is provided by diagnostic LEDs, which show operating and fault conditions at the front of the module.
