Product Description:

The DDS02.2-W050-BE46-02-FW is a digital AC servo drive controller manufactured by Bosch Rexroth Indramat as part of the DDS Drive Controllers series. Designed to command synchronous or asynchronous motors through closed-loop regulation, the unit integrates into modular automation cabinets where precise velocity and torque control are required. Its card frame accepts plug-in power, control, and communication modules so functions can be tailored without redesigning the entire axis. In operation, it supplies controlled motor current so the connected axis can respond accurately to commanded speed and torque values.

Its communication layer is based on the SERCOS interface, enabling deterministic drive networking on multimaster fiber rings. The power stage delivers a continuous output of 50 A, so upstream protection devices must be sized accordingly. The housing has an IP20 protection category, which is suitable for installation in a closed control cabinet. Thermal energy is removed by internal air cooling, so cabinet airflow must meet the required minimum velocity. The control board reads encoder data through digital servo feedback and resolver feedback, allowing one drive type to support multiple motor families without wiring changes. Reliable operation is maintained within an ambient range of 0 to 45 °C, which matches typical shop-floor climate control limits.

The controller’s altitude rating permits installation up to 1000 m above sea level without output derating. When powered down, the electronic assemblies can withstand storage temperatures from -30 to +85 °C, which supports transport and warehousing in unconditioned spaces. The operating program is not factory-loaded, and firmware must be ordered as a separate subitem. The unit is part of Line 02 and Version 2, which matches standard DDS auxiliary cards and mounting frames.
