Product Description:
The DMA 030A 1101-D is a servo drive module manufactured by Bosch Rexroth Indramat for the DMA Servo Drive Modules series. Installed on a cabinet backplane, it powers and controls a single motor axis in automated machinery. It converts DC link energy into three-phase output that drives synchronous or asynchronous servomotors with precise torque and speed regulation.
This model is a three-phase module for synchronous and asynchronous motors, an architecture that allows symmetrical drive of each phase. Its intermediate circuit operates at 670 VDC regulated / 715 VDC non-regulated, supplying the bridge that can deliver up to 35 Arms at 4 kHz switching frequency and 32 Arms at 8 kHz under open-loop conditions. When ambient temperature rises from 45 °C to 55 °C while running at 8 kHz, output capability is reduced by 0.35 A/K. Control electronics are supported by a 24 V auxiliary rail that draws only 1.23 A. Heat is removed through air cooling directed across the backplane, aided by a single internal fan, so no external ducts are required. Motion commands reach the module through a SERCOS setpoint interface, while a standard encoder interface returns position data. The drive plugs into an RMA/DM 30 backplane and follows the backplane mechanical format to simplify cabinet wiring.
With closed-loop regulation, the output is limited to 18 Arms at 4 kHz or 12 Arms at 8 kHz, figures suited to medium-frame servomotors used in conveyor or tooling axes. The module width of 50 mm and a mass of 7.3 kg let several units mount side by side without overloading light control panels. Cabinet heat rise remains controlled because worst-case dissipation is restricted to 180 W. Integrated one-axis positioning functions allow the controller to execute simple point-to-point moves locally, reducing traffic on the fieldbus and improving overall cycle times.
