Product Description:

The DDS02.1-W050-RS03-03-FW is a drive module produced by Bosch Rexroth Indramat for use within the DDS Drive Controllers series. Installed beside a compatible supply unit, it actuates Indramat synchronous or asynchronous servo motors in multi-axis machining centers, packaging lines, and handling systems. By regulating motor current and velocity according to real-time bus commands, the module forms the central power and control link between the machine control system and the mechanical load in industrial automation cells. This arrangement allows the drive to support controlled acceleration, steady running speed, and repeatable positioning on automated axes.

A primary communication path is the SERCOS interface, allowing deterministic command and status exchange with the motion controller over a fiber-optic ring. Thermal management relies on internal air cooling, meaning cabinet air is drawn through the heat sink instead of external fans, so clearance for airflow is required around the unit. The power stage is rated for 50 A, providing the current capacity needed for demanding servo operation in typical duty cycles. Position and speed loops obtain rotor angle through resolver feedback, which tolerates high temperatures and electrical noise. The drive belongs to Line 02. These features allow the controller to react quickly to commanded changes in speed and position during multi-axis operation.

Control functions are supplied as modular software, so the drive can be matched to the intended motion task after the required software package is installed. The drive is Version 1. In operation, the module serves as a digital AC servo drive controller and executes current, velocity, and position loops at cycle times set by the SERCOS master. This supports coordinated motion on machines that use several axes on a shared control platform.
