Product Description:

The DDS02.2-W050-BA03-01-FW is a digital AC servo drive controller built by Bosch Rexroth Indramat within the DDS Drive Controllers series. It coordinates power delivery to matched servo motors, interprets command signals, and provides closed-loop regulation for position, speed, or torque axes in automated machinery. By working with compatible motor feedback and higher-level motion controls, the unit forms the control link between the motion controller and the electromechanical load. It is intended for cabinet installation in protected industrial enclosures where the drive can be mounted near related control hardware. The controller is commonly used where repeatable motor response is needed across varying load conditions.

Signal exchange with the axis controller is accomplished through an analog interface, allowing continuous command voltages to set velocity or torque references. During operation, the power section can deliver a sustained current of 50 A, so the selected motor and duty cycle must remain within the controller’s operating range. Cooling relies on internal air cooling, meaning cabinet air moves across the heat sink and the enclosure must provide adequate ventilation. The housing carries an ingress rating of IP20, which limits installation to protected panels. Thermal limits permit full-load use from 0–45 °C, and the control loop can process either digital servo feedback or resolver feedback from the connected motor. This combination supports stable axis control while fitting standard control cabinet layouts.

Function code 01 combines with line code 02 and design version 2 to indicate the exact product configuration. When powered down, the controller tolerates storage between -30–85 °C without damage, which supports transport and storage in non-conditioned warehouse areas. It can be installed at elevations up to 1000 m before derating is required. These identification codes distinguish this unit from other DDS controller versions with different interfaces or output classes. The storage range also allows the drive to remain in inventory before installation without requiring climate-controlled handling.
