Product Description:
The DMA 08A 1301-D servo drive module is produced by Bosch Rexroth Indramat and belongs to the DMA Servo Drive Modules series. It is a three-phase power converter intended to supply synchronous and asynchronous motors in automated machinery. Within an installation, it occupies a single slot on a backplane rack and works with other Servodyn-D components to regulate speed and torque under closed-loop control. By delivering controlled AC output from a DC bus, it forms the actuator layer between the central motion controller and the plant’s mechanical loads, enabling coordinated axis movement in packaging, printing, and material-handling lines. This arrangement lets the controller manage acceleration, deceleration, and load response through the rack-mounted drive.
The module relies on backplane air cooling, so convective airflow drawn along the mounting rail removes heat without separate fans. Its housing is only 50 mm wide, allowing high axis density in multichannel racks. As a three-phase unit, it works from a shared DC link and generates three sinusoidal output phases for synchronous and asynchronous machines. Feedback enters through a resolver interface; the analog angle signal supplies rotor position during standstill, supporting quick restart after power recovery. The analog feedback path also supports stable low-speed control and accurate position tracking. For networked motion control, it communicates via the SERCOS interface, providing deterministic cyclic data exchange between the drive and the master controller.
The module is part of the Servodyn-D series, indicating mechanical compatibility with the same bus bars and signal connectors used across that line. It is the standard variant, so the diagnostic LEDs and parameter ranges match baseline drive tasks. There are no additional functions, and integrated protections such as overcurrent shutdown, overtemperature monitoring, and ground fault detection help protect connected motors and keep the DC link stable under fluctuating loads. These protections act directly in the power stage and respond automatically when operating limits are exceeded.
