Product Description:

The DMA 08A 1101-D is a servo drive module manufactured by Bosch Rexroth Indramat in the DMA Servo Drive Modules series. It serves as a three-phase power stage for automated machinery, supplying regulated current and voltage in response to motion commands from a higher-level controller. This allows the module to operate synchronous and asynchronous motors in positioning axes, conveyors, and other coordinated machine functions. In operation, the power stage supports controlled speed and torque output so the connected motion system can maintain accurate axis response.

This module occupies only 50 mm of panel width, so multiple axes can be mounted side by side without increasing cabinet size. Thermal management uses backplane air cooling, which moves heat into a shared air channel behind the rack instead of requiring separate fans on the front. Command and diagnostic data are transmitted through the SERCOS interface, and motor feedback is connected through a standard interface that supports common incremental or absolute encoder arrangements. The unit is described as a 3-phase module for synchronous and asynchronous motors, so the same power stage can be used with induction motors or permanent-magnet servo axes. Its narrow housing also helps when several drive modules must share one enclosure in a dense multi-axis layout.

The module includes no additional functions, so it is suited to applications that only need core drive operation. Internally, it belongs to the Servodyn-D series, and the delivered build is the standard variant. That version does not include protective coatings, extended-temperature components, or option cards, and matching cables and accessories are available for this drive format in multi-axis systems. The layout remains focused on the main power and control tasks of the axis without adding optional hardware.
