Product Description:
The DMA 30A 7301-D servo drive module is manufactured by Bosch Rexroth Indramat as part of the DMA Servo Drive Modules series. It mounts on a common DC bus rail and supplies regulated power to synchronous and asynchronous motors used in automated conveyors, pick-and-place stations, and press drives. In servo systems, the module acts as the power stage between the motion controller and the motor, allowing commanded torque and speed changes to be carried out with a fast electrical response. By converting DC bus power into variable-frequency output, the unit links higher-level motion controllers with field motors and completes the electric axis loop inside the cabinet.
Mechanical integration is streamlined by a module width of 50 mm, allowing several axes to sit side by side without exceeding standard rack spacing. Its narrow housing also helps preserve room for neighboring modules, bus bars, and signal routing in compact control cabinets. Thermal dissipation is handled through backplane air cooling, so airflow along the rear panel removes switching heat without requiring an external liquid circuit. The device energizes motors on a three-phase bus, providing symmetrical line-to-line voltages that match industrial windings. Rotor feedback is accepted through a resolver interface, giving position signals that remain stable under electrical noise and high acceleration.
For plant networking, a CANrho communication port conveys status words and setpoints directly over a CAN backbone without separate gateways. This arrangement reduces extra point-to-point control wiring and allows the drive to exchange operating data with the rest of the machine over a shared network. The hardware includes no additional functions, so the feature set remains limited to the base drive functions. The electronics use the Standard Variant profile, and the current ratings follow the baseline values for this drive type. Within the Servodyn-D series, the module uses the same address layout and diagnostic structure as related units.
