Product Description:

The DDS02.1-W050-RA02-02-FW is a digital AC servo drive controller produced by Bosch Rexroth Indramat and assigned to the DDS Drive Controllers series. It converts power from a regulated DC bus into commanded motor current for a compatible synchronous or induction motor. In an automation cell, the unit closes the loop between the machine PLC and the motor shaft through real-time feedback processing. By managing speed, torque, and position in real time, the controller supports coordinated multi-axis motion in packaging, printing, and material-handling equipment. This operating pattern is common on indexing tables, web-handling sections, and transfer axes where several motors must react together.

Command and diagnostic exchange with the drive occurs through its analog interface, so the host controller adjusts velocity or torque by varying reference voltages instead of sending network messages. This arrangement suits systems that use conventional analog command wiring and require direct handling of speed or torque references at the drive. Thermal management relies on internal air cooling, meaning cabinet air moves across the heat sink and enclosure airflow must be maintained during operation. The power stage delivers a continuous 50 A of output current, which sets the motor RMS demand the unit can support during steady operation without overcurrent shutdown. Rotor position is captured through resolver feedback, so the connected motor must use the corresponding feedback device for closed-loop control. Application-specific parameters are stored in a removable memory module, which keeps setup data with the module and preserves the configured drive data.

The device belongs to Line 02. It is built as Version 1 within that line. The line code separates this controller from earlier releases, while the version code identifies the initial production build within that line. These codes identify the controller variant used for this model and correspond to the documented mechanical layout and connector arrangement.
