Product Description:

The DDS02.2-A100-BE30-01-FW is a digital AC servo drive controller produced by Bosch Rexroth Indramat for the DDS Drive Controllers series. It supplies regulated three-phase power and closed-loop control signals to matched servo motors in automated machinery, translating PLC commands into precise current, speed, and position regulation. The unit fits into modular drive stacks where multiple axes share a common DC bus, supporting synchronized motion sequences on assembly lines, handling systems, and packaging equipment. Because it works in a shared-bus system, the controller can be combined with other axes in the same rack without a separate power conversion stage for each motor. This layout supports compact multi-axis installations where coordinated motion is required across several machine functions.

The drive exchanges real-time parameters with the host via the SERCOS interface, a deterministic fiber-optic bus that supports cycle times down to 1 ms for tight axis coordination. Its power stage delivers a continuous current of 100 A, giving headroom for high-torque acceleration on medium and large motors. Protection is rated at IP20, so the device must be installed inside a cabinet to guard against dust and accidental contact. Heat is removed by external air cooling, which moves ambient air from outside the enclosure across the heat sink. Cabinet layouts must provide a clear airflow path so the cooling stream can pass through the heat sink effectively. Stable operation is permitted in ambient temperatures from 0 °C to 45 °C when cabinet conditions remain within that range.

The controller can be installed at elevations up to 1000 m above sea level without performance loss. Dual digital servo feedback and resolver feedback inputs allow it to accept either encoder format for position control, which is useful in both new systems and retrofit applications. This helps when existing machines use resolver-based motors and newer axes use digital feedback. The unit carries Function ID version 01, belongs to Line 02, and is version 2. A storage temperature window of -30 °C to +85 °C protects internal components while the drive is unpowered during transport or storage.
