Product Description:

The DDS02.2-W200-BE77-00-FW is a digital AC servo drive controller produced by Bosch Rexroth Indramat in the DDS Drive Controllers series. Installed in a common DC-bus cabinet, it converts the shared supply voltage into a regulated three-phase output for synchronous or induction servomotors. In automated machine tools, packaging systems, and material-handling gantries, the unit serves as the link between higher-level motion logic and the mechanical axis. This arrangement keeps the power electronics centralized in the cabinet while the motors remain at the machine axes, which is typical in multi-axis industrial drive systems.

The controller supplies up to 200 A of continuous motor phase current, so connected axes can sustain high load demand during acceleration and process changes. For deterministic communication, it uses the SERCOS interface, allowing real-time setpoint transfer and synchronized sampling across the optical ring. Thermal management relies on air drawn from inside the control cabinet, so cabinet ventilation must remove the added heat instead of relying on room air alone. Position feedback can use digital servo feedback and resolver feedback, which supports either high-resolution encoders or rugged resolver transducers without external signal converters.

The unit is part of Line 02, so its mounting dimensions and connector positions follow the second DDS generation. The hardware is Version 2, which matches the parameter structure used by later SERCOS masters. Shared heat sink geometry, DC-bus jumper placement, and diagnostic access help it fit alongside companion axes in the same platform. This layout keeps the electrical and mechanical arrangement consistent across related units and makes enclosure planning more predictable when several axes are installed side by side.
