Product Description:
The DMA 45A 4101-D servo drive module is manufactured by Bosch Rexroth Indramat and belongs to the DMA Servo Drive Modules series. It is intended for three-phase supply of synchronous or asynchronous motors in automation lines, where it provides regulated current, velocity, and position control through a shared rack backplane. Mounted alongside matching power supplies and axis cards, the module helps build compact multi-axis systems that fit into machine tool enclosures, packaging machinery, or material-handling stations without extensive rewiring. This arrangement keeps power and control functions centralized within the rack and supports orderly cabinet integration.
With a width of 50 mm, the module conserves panel space and leaves room for adjacent wiring ducts. Thermal management relies on backplane air cooling, so heat is carried away through the rack rather than by front-mounted fans. Motor feedback is routed through a standard interface, and command values can be exchanged through an analog interface with 16-bit resolution for fine current and speed adjustment. Because the unit is a three-phase module, it connects directly to three-phase mains and delivers balanced output to both synchronous and asynchronous motors. This layout suits cabinets where multiple axes must be arranged closely, and the narrow housing helps preserve working clearance around neighboring terminals and plug-in modules.
The drive has no integrated logic blocks, so external safety relays or fieldbus couplers can be added when required by the machine design. Its parameter structure follows the Servodyn-D series convention, which helps keep rack-level integration consistent across compatible axes and associated control cards. Hardware is supplied in the standard variant, without special option overlays on the base module. The unit uses standard electrical limits and connector layout for installation in compatible racks.
