Product Description:

The DMA 30A 4101-D drive module is part of the DMA Servo Drive Modules series manufactured by Bosch Rexroth Indramat. It serves as the power stage for synchronous and asynchronous motors, sitting between the mains supply and the motor windings in automated machinery. In an Indramat multi-axis rack, the module converts incoming DC bus energy into controlled phase currents so that connected axes can follow speed, torque, and position commands in packaging lines, material handling systems, and other motion platforms. This arrangement lets several drive sections share a common rack structure while each axis is controlled independently.

Thermal management uses backplane air cooling, so waste heat is removed by airflow across the rear heat sink after the unit is installed in the rack. The housing width of 50 mm helps conserve panel space and allows multiple axes to be mounted side by side without obstructing airflow. Command values are processed through an analog input with 16-bit resolution, which provides 65,536 discrete steps for smooth motor response during speed or torque control. Motor feedback is accepted through a standard feedback interface, allowing the drive to process incremental encoder signals without additional adapters. The narrow housing is useful in compact cabinets where several drive channels must fit within a limited enclosure width.

The module is a three-phase module for synchronous and asynchronous motors, so it can supply balanced current to each stator phase while supporting different motor types on the same DC link. It is supplied as a standard variant and comes with no optional extras. The baseline configuration keeps the connector set and operating functions straightforward for standard installations. It is also part of the Servodyn-D series, which places it within the matching rack platform used for coordinated multi-axis drive systems.
