Product Description:
The DDS02.2-W050-BE11-02-FW is a digital AC servo drive controller manufactured by Bosch Rexroth Indramat and part of the DDS Drive Controllers series. It forms the central actuation layer between higher-level motion control and the power stage that energizes compatible servo motors. It works as the regulated interface that translates incoming control data into controlled motor current for servo-driven machine axes. By modulating voltage and current in real time, the unit maintains commanded velocity and position profiles for automated machinery such as packaging lines, pick-and-place systems, and material-handling axes.
Communication with the supervisory controller occurs through a SERCOS interface, allowing deterministic exchange of setpoints and status data over fiber-optic rings. The optical link supports precise timing between axes and helps the drive respond consistently to motion commands. Thermal losses are removed by internal air cooling, because the blower moves cabinet air across the heat sink rather than relying on external ducting. The power stage is rated for 50 A, so the axis drive can deliver substantial acceleration current during dynamic operation. An IP20 enclosure rating limits its use to closed panels but supports compact mounting in control cabinets. Operation is permitted at ambient temperatures from 0 to 45 °C. The controller belongs to line 02 and is supplied as version 2.
Long-term storage is permissible between -30 to 85 °C, which helps protect passive components while the unit is transported or held as spare inventory. Installation sites up to 1000 m above sea level are supported without output adjustment, so typical plant elevations do not require special compensation. For position feedback, the drive accepts Digital servo feedback signals as well as Resolver feedback, allowing it to operate with motors equipped with either high-resolution encoders or resolver-based sensing. This allows the same drive type to work with different motor feedback devices on one machine.
