Product Description:

The DDS02.1-A150-DA07-02-FW is a drive controller produced by Bosch Rexroth Indramat and assigned to the DDS Drive Controllers series. As a digital AC servo drive controller, it regulates current and velocity loops for Indramat synchronous and induction motors used in machine tools, handling systems, and other industrial axes. The unit receives control signals from higher-level motion hardware and provides closed-loop torque and speed regulation during dynamic operation. It serves as the electrical interface between the cabinet power stage and the connected motor, allowing the axis to respond smoothly to changing load demands. Its compact cabinet-mounted format combines power electronics and signal processing in one module, which helps keep multi-axis installations orderly.

The controller supplies up to 150 A of continuous output current for motors that require substantial sustained current. Incoming position and speed data are handled through digital servo feedback, while command values are received over an analog interface, making the unit suitable for systems that use analog command signals. This combination supports precise motor regulation without requiring a digital network interface for the command channel. Heat is removed by external air from outside the control cabinet, so the installation must provide a clear airflow path across the power section. The enclosure has an IP20 protection rating, which means the controller is intended for installation inside a protective cabinet rather than in an exposed location.

The controller operates in ambient temperatures from 0 to 45 °C and at elevations up to 1000 m above sea level without current derating. For storage, it tolerates temperatures from -30 to 85 °C when it is not in service, which helps it remain suitable for transport and warehouse conditions. Storage outside that range can place unnecessary stress on insulation materials and electronic assemblies. The hardware belongs to line 02 with revision 1, matching the DDS platform connection scheme used for this design. These operating limits apply to normal enclosed-cabinet use, where temperature control and airflow remain important to stable drive performance.
