Product Description:

The DDS02.1-A150-DS52-00-FW is a modular drive controller produced by Bosch Rexroth Indramat and assigned to the DDS Drive Controllers series. Installed inside a control cabinet, it governs the current, velocity, and position loops of an AC servo axis, converting motion commands from a PLC into precise switching patterns for the connected power transistors. By handling these time-critical tasks, the unit reduces the load on the central control system and keeps torque response repeatable across multiple axes in an automated production line. Because regulation occurs locally in the controller, the connected motor can respond to changing loads without relying on constant correction from the higher-level PLC.

Communication with higher-level motion processors is handled through the SERCOS interface, a deterministic fiber-optic ring that exchanges command and feedback data at fixed cycle times. The power stage can deliver a continuous current of 150 A, which supports rapid acceleration in positioning tables or gantry drives. Thermal management relies on external air cooling, with ambient air directed across the heat sink so internal electronics remain within limits when several drives are mounted side by side. Encoder data arrive via digital servo feedback, which carries position information and diagnostic data in a single shielded cable and helps the controller correct speed or position deviations during load changes. The controller belongs to Line 02, allowing it to mount on common DC bus bars and rails used by compatible supply and auxiliary modules.

The drive is Version 1. The required firmware is ordered separately, so the software package can be selected for the intended machine function instead of being supplied as a fixed onboard set. This arrangement separates the core power electronics from the software selection and suits installations in packaging machines, presses, and palletizers that use the same motion platform.
