Product Description:

The DDS02.1-A025-RA01-00/S002 is a digital AC servo drive controller produced by Bosch Rexroth Indramat for the DDS Drive Controllers series. It regulates motor current and velocity while interfacing with a higher-level motion control system for synchronous or induction servo motors in handling, packaging, and machining equipment. By combining the power section, protective functions, and feedback processing in one enclosure, the unit reduces cabinet space and simplifies axis integration in multi-drive systems. Its layout is intended for applications that need compact control hardware without separating the amplifier and feedback interface into different modules. This makes it suitable for axes that must respond predictably during starting, stopping, and speed changes.

Control commands enter through an analog interface, so speed or torque references are supplied as standard voltage signals. This arrangement fits controllers that output conventional analog references rather than digital fieldbus commands, which keeps signal handling straightforward in retrofit systems and other established machine platforms. Thermal management uses external air cooling, with airflow drawn from outside the cabinet to remove heat from the heatsink and support stable operation under continuous load. The power stage delivers a continuous motor current of 25 A, which suits medium-power axes that need steady torque during acceleration and process changes. The enclosure has an IP20 rating, which helps protect against accidental contact with live conductors in enclosed installations. Rotor position is monitored through resolver feedback, allowing the drive to calculate rotor angle continuously and maintain smooth vector control at low and moderate speeds.

The permissible service environment spans 0 to 45 °C, allowing the drive to operate alongside other control equipment in standard industrial cabinets. For transport and storage, the unit tolerates -30 to 85 °C, which helps protect internal materials during seasonal temperature changes. Rated performance applies up to 1000 m above sea level before cooling or load derating may be required. The unit carries Function ID 01 within the type code. It is also assigned to line 02 with hardware version 1, which helps identify the matching control configuration for this model.
