Product Description:

The DMA 15A 4101-D is a servo drive module manufactured by Bosch Rexroth Indramat as part of the DMA Servo Drive Modules series. Installed on a common DC bus inside motion cabinets, the unit converts shared link voltage into three regulated output phases for motor windings. It serves as the power stage between a motion controller and a synchronous or asynchronous motor, supplying the controlled current needed for precise axis positioning in packaging, material handling, and printing equipment. Its compact form is suited to multi-axis assemblies where cabinet space is limited and modular layout is important. Because it operates from a common DC bus, several axes can share the same cabinet power structure without separate input converters for each module.

Heat is removed by backplane air cooling, so airflow behind the heat sink keeps semiconductor temperatures under control without a front-mounted fan. The housing has a width of 50 mm, which helps several axes fit side by side in a narrow rack. Command data are accepted through an analog setpoint with 16-bit resolution, giving fine control over velocity or torque reference changes. Power connections align with dedicated backplane slots, so the module installs directly into the rack and leaves the front area available for signal and motor wiring.

The additional-function register indicates no additional functions, so the module remains focused on core drive operation. Feedback is handled through a standard interface, allowing connection to compatible incremental or absolute encoders used in Rexroth motion systems. The unit is a 3-phase module for synchronous and asynchronous motors, which makes it suitable for machines that use different motor types on the same DC-bus platform. It is part of the Servodyn-D series, and it is supplied in a standard version. In this standard version, the module does not include extra function hardware.
