Product Description:

The DMA 45A 8001-D drive module is manufactured by Bosch Rexroth Indramat and belongs to the DMA Servo Drive Modules series. Serving as a compact control element for multi-axis motion platforms, the unit supplies regulated three-phase power to compatible motors in automated machinery. By slotting into a Servodyn-D backplane rack, the module links directly with higher-level controllers, enabling precise torque, speed, and position regulation within packaging lines, printing presses, and material handling systems. This rack-based arrangement also supports coordinated axis operation without requiring each drive to use a separate stand-alone enclosure.

Within the rack, heat dissipation is managed through backplane air cooling, so airflow drawn along the card cage keeps the power electronics within their allowable temperature range without requiring an integral fan on the module. The housing occupies a footprint only 50 mm wide, permitting dense side-by-side installation when multiple axes are needed in limited cabinet space. Command values reach the power stage via a 10-bit analog U/f interface, giving the controller proportional control over output voltage and frequency through a simple analog reference path. The module has no external encoder interface, so any separate position-feedback handling remains outside this card.

As a 3-phase module for synchronous and asynchronous motors, the unit delivers phase-balanced current patterns that match the operating requirements of permanent-magnet and induction machines linked to the rack. The drive is identified as part of the Servodyn-D series, which clarifies compatibility with bus supplies, sensor boards, and neighboring axes in the same platform. The card has no auxiliary or safety functions, so those tasks remain with the host PLC or other system-level control hardware. The design follows the standard variant, and its parameter files remain aligned with factory defaults rather than a custom application-specific build.
