Product Description:

The DDS02.2-W050-BT21-01-FW is a digital AC servo drive manufactured by Bosch Rexroth Indramat for the DDS Drive Controllers series. Installed inside a control cabinet, the unit interfaces with synchronous or asynchronous servo motors to adjust torque, velocity, and position in automated production cells. Its control electronics close the feedback loop between the drive and motor transducer so machining centers, pick-and-place axes, and packaging stations receive repeatable motion profiles. It is suited for machine functions that require coordinated starts, stops, and speed changes across repetitive production cycles.

The drive can deliver a continuous output current of 50 A, allowing connected axes to accelerate heavy loads without derating. Its enclosure carries an IP20 rating, which protects against finger contact while leaving ventilation openings unobstructed. This enclosure style is intended for protected indoor installation rather than direct exposure on the machine frame. Thermal management relies on internal air cooling, so cabinet air moves across the heat sink and the cabinet layout must provide clearance for airflow. Reliable control is supported by digital servo feedback, which lets the controller read high-resolution position data directly from the motor encoder. The electronics remain functional within an ambient range of 0 to 45 °C, matching typical shop floor conditions without auxiliary chillers.

Application planning should respect the maximum installation altitude of 1000 m, because thinner air above this level reduces cooling effectiveness. When the controller is not energized, it tolerates storage temperatures from -30 to 85 °C. This wider storage range supports transport and storage in unconditioned spaces. In addition to the digital channel, the unit can interpret resolver feedback, so legacy motors can be used with the same axis card. The parameter structure uses Function ID version 01 and corresponds to the Line 02 and Version 2 configuration of the unit.
