Product Description:
The DDS02.2-A100-BE43-02-FW is a drive module produced by Bosch Rexroth Indramat in the DDS Drive Controllers series. Designed for cabinet mounting, it governs AC servo motors through torque, speed, and position loops within decentralized automation cells. By converting command data from a higher-level motion system into regulated current, it links the plant controller with individual motors. This allows the unit to act as the main actuator interface in machining centers, material-handling equipment, and packaging lines where accurate axis response is required during repeated operating cycles.
Communication with the supervisory PLC occurs through the SERCOS interface, a fiber-optic ring that carries cyclic command data and diagnostic messages. This deterministic channel supports synchronized multi-axis updates to 62.5 μs, which helps coordinated axes respond at the same control interval. The unit uses external air cooling, so ambient air from outside the enclosure passes across the heat sink and removes switching losses without raising the internal cabinet temperature. A continuous bus current of 100 A is available, allowing the drive to support high dynamic motor demand during acceleration and load changes. Feedback from the machine side may be provided by digital servo feedback for high-resolution position data or by resolver feedback for a more rugged sensing method in electrically noisy environments.
The drive belongs to Line 02 and is identified as Version 2, so it follows the parameter structure and diagnostic format used by second-generation DDS devices. It uses the same mechanical mounting pattern and pinout as compatible components in the platform, which supports orderly installation in multi-axis cabinet layouts. This arrangement helps the drive fit with matching power sections, interface modules, and mains supplies without changing the overall module layout. Consistent connector placement also helps keep cable routing clear in systems that group several drive modules side by side.
