Product Description:

The DMA 45A 9301-D is a drive module produced by Bosch Rexroth Indramat for the DMA Servo Drive Modules series. It functions as a control stage for three-phase synchronous and asynchronous motors in automated machinery, supplying the regulated current needed for precise motion in a multi-axis system. Because it serves as a modular drive element rather than a self-contained controller, it is intended to operate alongside matching supply and system components. This arrangement suits machinery where several axes must be coordinated from one drive platform.

This module uses backplane air cooling, so cabinet ventilation must accommodate the specified exhaust path. A built-in resolver interface accepts sinusoidal feedback signals for motor commutation and position tracking, which supports stable motor synchronization during operation. Fieldbus connectivity is provided through CANopen and CANrho, which carry parameter data and cyclic setpoints to higher-level controllers. The housing has a width of 50 mm, allowing tight module spacing without crowding the installation area, and the narrow profile helps preserve panel space for neighboring units. It is a 3-phase module for synchronous and asynchronous motors, so it is intended for balanced three-phase drive systems. The unit has no supplementary option cards, and all available functions are provided on the base board.

The hardware is supplied as the standard variant, matching the generic performance envelope used across the Servodyn-D series. Diagnostic data, fault codes, and operating statistics are mapped into a shared CAN object dictionary used by companion axis inverters. This common data structure keeps status handling and parameter access consistent across related modules in the same drive system. It also supports integration in multi-axis assemblies where several inverters exchange operating information over the network.
