Product Description:

The DDS03.1-W050-DS01-01 is a digital AC servo drive controller produced by Bosch Rexroth Indramat as part of the DDS Drive Controllers series. The unit receives a stabilized DC bus from an Indramat supply module, modulates that energy into a precisely timed three-phase output for a connected servo motor, and communicates real-time status with higher-level motion processors. By regulating torque, velocity, and position through closed-loop commands, it serves as the actuator interface in automated assembly stations, pick-and-place gantries, and other equipment that requires synchronized axis control.

The controller exchanges motion data over the SERCOS interface, a fiber-optic network that provides deterministic timing and noise immunity in multi-axis systems. Its power stage is rated at 50 A, meaning the drive can continuously deliver that output current without exceeding thermal limits when mounted inside a cabinet. Because the housing has an IP20 rating, the electronics must remain inside an enclosure, but they do not require additional sealing against accidental contact with internal components. Heat is removed by internal air cooling, which uses airflow drawn from within the control cabinet instead of an external blower path. Installation altitude can reach 1000 m above sea level without derating, allowing full current capability in most plant environments.

Motor position is returned through digital servo feedback, enabling high-resolution monitoring and automatic commutation after each power cycle. Reliable function is maintained across an ambient range of 0 to 45 °C, while the electronics tolerate storage or transport from -30 to 85 °C without damage. The product belongs to Line 03 and carries Function ID 01 with Function ID Version 01. It is supplied as Version 1 hardware and is intended for use in closed cabinets alongside other DDS modules.
