Product Description:
The DDS03.1-W030-RC01-01 is a digital AC servo drive controller manufactured by Bosch Rexroth Indramat and supplied within the DDS Drive Controllers series. As a controller, it provides closed-loop power conversion for synchronous and induction motors used in positioning, printing, and material-handling stations. By managing current, velocity, and position commands, the unit links the higher-level motion controller to the mechanical axis and supports repeatable motion in automated equipment. This arrangement lets the drive respond quickly to changing load conditions during acceleration, deceleration, and holding phases in coordinated machine processes.
The drive delivers a continuous output of 30 A, enabling it to pair with medium-frame motors that demand steady torque. Electrical safety inside a cabinet is addressed with an IP20 protection rating, which helps prevent accidental contact with live parts while the surrounding enclosure provides additional protection. Thermal management is achieved through internal air cooling, so ambient cabinet air passes over the heat sink without requiring separate external fan trays. For networked control, the unit carries an INTERBUS-S interface, allowing cyclic data exchange with a PLC for command handling, diagnostics, and parameter data. Rotor position is returned to the controller through resolver feedback, which provides robust angle information in electrically noisy and thermally demanding motor environments. That feedback method is often used where stable signal quality is important across long motor cable runs.
The allowable ambient range spans 0–45 °C during operation and -30 to 85 °C in storage, so the unit can remain in typical industrial cabinets during service and standby periods. Reliable performance is maintained up to 1000 m installation altitude, matching common plant elevations without derating. The unit carries Function ID 01 with Function ID Version 01, Line 03, and Version 1. These codes identify the control configuration used for this model and keep the drive description consistent within its product line.
