Product Description:
The DMA 45A 1101-D drive module belongs to the DMA Servo Drive Modules series and is produced by Bosch Rexroth Indramat. Designed as a cabinet-mounted power stage, it supplies regulated three-phase power to both synchronous and asynchronous motors used in industrial automation. The regulated output is intended to support precise motor response during automated machine cycles. By linking motion axes to a centralized DC bus, the module supports coordinated positioning, speed, and torque control across multi-drive systems. This arrangement helps a machine use a common power structure while separate axes respond to commands from the higher-level control system.
The module occupies only 50 mm of rack width, so high-axis density is possible inside a standard 19-inch enclosure. Cooling is handled by backplane air cooling, which moves heat behind the module so front wiring remains undisturbed and access to terminals stays clear. Feedback information from connected motors is accepted through a standard interface, simplifying encoder connectivity without optional add-on boards. Real-time command and diagnostic data reach the module over the SERCOS interface, which supports deterministic cycle times when the drive is connected to PLC-based motion control in coordinated automation cells.
As a three-phase module intended for both synchronous and asynchronous motors, the DMA 45A 1101-D supports mixed-motor installations without requiring separate inverters. The hardware presented here is the standard variant, so no optional fieldbus add-ons or extended safety boards are factory-mounted. The module has no additional functions listed, so application behavior is directed by the upstream motion controller. It also carries the Servodyn-D series designation, indicating placement within that drive platform.
