Product Description:

The DDS02.1-W025-RA01-00 is a digital AC servo drive controller produced by Bosch Rexroth Indramat for the DDS Drive Controllers series. Within an automation rack, it receives commanded setpoints and modulates current to the connected servo motor so that torque and speed follow the control loop precisely. The device is intended for cabinet installation in industrial motion systems where multiple axes share a common DC bus and the controller supervises coordinated positioning tasks. Its control section helps the axis respond smoothly during acceleration, speed changes, and steady-state operation.

This model communicates with the higher-level control system through an analog interface, allowing continuous reference signals instead of discrete fieldbus words. It can supply up to 25 A of output current, which indicates the motor load it can support without exceeding thermal limits. Heat is removed by internal air cooling, so airflow drawn from inside the cabinet passes over the heat sink and the enclosure must provide adequate ventilation. The housing carries an IP20 protection category, indicating finger-safe construction but no sealing against airborne dust. Reliable operation is maintained between 0 to 45 °C, which suits typical industrial control cabinet conditions. Function ID 01 is preset for this model, so its command structure follows that assigned function.

The unit withstands storage temperatures from -30 to +85 °C, permitting shipment or storage in non-conditioned warehouses. A maximum installation height of 1000 m above sea level keeps cooling and insulation behavior within the intended operating range. Motor position and speed are returned through resolver feedback, so the attached servo must use a compatible resolver. The unit belongs to line 02 of the family, and the electronic assembly is identified as version 1.
