Product Description:
The Bosch Rexroth Indramat DMA 45A 1201-D servo drive module belongs to the DMA Servo Drive Modules series. It operates as the power and control element that links motion controllers to machine-mounted motors, regulating velocity and torque in automated packaging, material handling, and assembly stations. Integration into a backplane rack allows compact installation and shared DC bus connections across multiple axes. Because the drive electronics are concentrated in a rack-mounted module, the system can centralize control hardware while still delivering precise response at each driven axis.
The thermal design relies on backplane air cooling, so exhaust heat is carried away through the cabinet duct rather than by a dedicated front fan. With a chassis width of 50 mm, the module occupies one narrow slot, which leaves room for several drive channels in a confined control cabinet. Communication takes place over a SERCOS interface, providing deterministic cycle times for axis coordination and diagnostic feedback. Motor position data are accepted through the dedicated gear encoder input, allowing the drive to work with geared feedback devices for high-resolution speed control. The combination of deterministic communication and dedicated feedback handling supports stable synchronization in applications that use ratio control, electronic gearing, or matched conveyor sections. It is a 3-phase module for synchronous and asynchronous motors, so it can supply field-oriented current to permanent-magnet and induction machines without additional hardware.
The additional functions field is marked no additional functions, which keeps the configuration focused on standard motion tasks. Internally, the unit uses the Servodyn-D series architecture, so parameter structures and service tools match other devices built on the same platform. The hardware supplied here is the standard variant, with rated current, protection limits, and connector layout aligned with the baseline product version. This makes the module suitable for installations that need the core motion features of the platform without added option boards or special hardware extensions.
