Product Description:

The DDS03.1-W030-DS40-02-FW belongs to the DDS Drive Controllers series produced by Bosch Rexroth Indramat. As a modular digital AC drive controller, it coordinates torque, speed, and position loops for servo motors in factory automation lines and processing machinery. Integrated within a multi-axis rack, the unit connects to the central supply module to provide regulated power and closed-loop control for attached servo axes. This arrangement allows one controller position in the rack to manage acceleration, steady running, and controlled stopping for a connected motor.

Its communication backbone is the SERCOS interface, allowing deterministic real-time exchange with upstream CNC or PLC hardware. Motor position is returned through digital servo feedback, so each drive can process precise motion data without additional resolver converters. During continuous motion, it can deliver 30 A of output current, and heat generated by the power stage is removed by air drawn from inside the control cabinet. This internal airflow matches the drive’s IP20 protection class, which assumes installation in an enclosed panel. Reliable operation is permitted at ambient temperatures from 0 to 45 °C, which suits standard industrial control cabinets. Because the feedback signals are handled directly by the controller, the drive supports accurate axis response during positioning and synchronized machine movement.

For projects installed at elevations up to 1000 m above sea level, no adjustment to current or switching frequency is required. Long-term warehouse or transport conditions are tolerated between -30 to 85 °C, which helps protect the unit before installation. The hardware is in Line 03 and uses design version 1. These identifiers indicate the product generation within the DDS platform. Application software is supplied separately, so the controller can be matched to the required motion function of the machine.
