Product Description:

The DDS 3.1-W050-DS12-01 is a drive controller manufactured by Bosch Rexroth Indramat as part of the DDS Drive Controllers series. Classified as a Digital AC Servo Drive Controller, it converts DC bus energy into controlled three-phase output for servo motors used in industrial automation cells. By linking with higher-level PLCs and motion processors, the unit carries out precise torque and velocity commands for packaging lines, printing presses, and multi-axis transfer systems. This arrangement lets the drive translate software-based motion instructions into regulated electrical output and repeatable mechanical movement.

Communication with the supervisory control layer is handled through the SERCOS interface, which provides real-time telegrams for synchronized motion across multiple axes. Cooling uses air from inside the control cabinet, so enclosure airflow must be sufficient to keep the heat sink within its operating limit. The power section is rated for 50 A of continuous motor phase current. With an IP20 enclosure rating and an operating ambient range of 0 to 45 °C, the controller is intended for installation in enclosed electrical panels, and external protection must be provided against dust and moisture.

For storage and shipment, the electronics can withstand temperatures from -30 to 85 °C without being powered. The unit can be operated at elevations up to 1000 m above sea level; beyond that height, reduced air density can limit cooling performance. Position and speed signals are processed through digital servo feedback, which supports accurate closed-loop control of the connected motor. This feedback method allows the drive to read rotor position and speed data directly during operation. The controller uses Function ID 01 and hardware version 1 for this configuration. These identifiers indicate the configured control version of the unit.
