Product Description:
The DMA 30A 1301-D servo drive module is built by Bosch Rexroth Indramat and belongs to the DMA Servo Drive Modules series. It is a three-phase power stage that pairs with synchronous or asynchronous motors and forwards motion commands from a master controller. This arrangement lets the unit support controlled acceleration, deceleration, and steady-state running in multi-axis equipment. In industrial automation, the module conditions incoming line voltage, measures motor feedback, and adjusts output current so that each axis follows its programmed velocity and positioning profile.
The drive expels heat through backplane air cooling, meaning cabinet airflow drawn across the rear heat sink is enough to keep semiconductor temperatures within their rated range. A compact housing width of 50 mm allows the unit to fit densely on DIN rails with minimal panel space. The narrow width also leaves room for neighboring drives, terminals, and cable routing in compact enclosures. Command and status data move over the fiber-optic SERCOS interface, which supports deterministic cyclic communication between multiple drives and the central PLC. Rotor position is detected through resolver feedback; the analog windings in the transducer provide absolute angle information even during standstill, enabling smooth startup and reliable commutation. The hardware is a three-phase module, so its output bridge energizes motor windings on all three phases and can return regenerative energy to the DC bus during deceleration.
The module has no optional expansion cards, so cabinet wiring stays simple and there are no extra plug-in functions or connectors to route within the panel. It uses the Standard Variant configuration, which indicates the regular version of this module rather than a special option set. The internal architecture aligns with the Servodyn-D series platform, which uses common control logic and diagnostics across different power ratings. Across the platform, the shared diagnostic structure keeps status reporting consistent between axes of different power classes.
