Product Description:

The DDS02.1-A150-RC01-01-FW belongs to the Bosch Rexroth Indramat DDS Drive Controllers series. This digital AC servo drive controller regulates phase currents for synchronous and induction servo motors used in automated assembly lines, packaging machines, and material-handling axes. It can serve as the power stage between a DC bus supply and a compatible motor, converting control commands into regulated motor current. By closing the current loop near the motor, it reduces the processing load on the motion controller and delivers real-time torque commands to the mechanical system.

The drive exchanges cyclic process data through the INTERBUS-S interface, simplifying multi-axis networking with standard bus cables. The bus link carries command values and status information between the controller and the higher-level automation system. It relies on external air cooling, so ambient air drawn from outside the cabinet removes the heat generated by its power electronics. This cooling method requires a cabinet layout that can route clean air across the heat sink. A rated output of 150 A supports high-torque motors in demanding servo axes. The enclosure has an IP20 rating, so the controller is intended for installation inside protected electrical cabinets rather than exposed machine surfaces. Operation is permitted in ambient temperatures from 0–45 °C, where the control section maintains stable gate timing and current regulation.

Installation above 1000 m is not recommended because reduced air density lowers cooling effectiveness. The drive accepts position feedback from motors equipped with resolver feedback, allowing noise-tolerant angle measurement without digital encoders. This feedback method remains useful where vibration or electrical noise makes more sensitive feedback devices less practical. For warehouse storage or transport, it withstands temperatures from -30 to +85 °C, which helps protect internal components during seasonal temperature changes. The controller carries Function ID 01 for this drive family.
