Product Description:

The DDS02.1-W015-DA02-01-FW is a digital AC servo drive controller produced by Bosch Rexroth Indramat within the DDS Drive Controllers series. It regulates torque, speed, and position for synchronous and induction motors in modular automation racks, supplying closed-loop current to the motor phases while exchanging status data with higher-level PLCs. In an assembly line or machine tool, the unit translates low-level command voltages into controlled three-phase power for the attached motor. The module accepts axis commands, modulates the shared DC bus, and issues phase-synchronized output to the connected motor section. Its role is to turn the shared supply into motor-specific output while maintaining stable axis behavior during acceleration and deceleration.

Communication with the upstream control system uses an analog interface, so speed or torque setpoints arrive as differential voltages rather than through a fieldbus link. Heat is removed by internal air cooling, so cabinet air passes the heat sink and exits through ventilation slots. The drive supplies a continuous output of 15 A, and current is regulated with the motor’s digital servo feedback so the controller can respond quickly to load changes. The enclosure meets IP20, which is suitable for protected installation inside a closed panel. This control method suits systems that use analog command sources and separate motion logic. The unit belongs to Line 02 and carries Function ID 01.

The controller operates at ambient temperatures of 0 – 45 °C without derating and can be stored between −30 – 85 °C when it is not in service. Installation is allowed up to 1000 m altitude, and above that height additional cooling is needed because thinner air removes less heat from the internal surfaces. The controller is Version 1, which identifies the first hardware release in this model line. These limits should be observed when the unit is mounted beside other rack modules that can restrict internal cabinet airflow.
