Product Description:

The DDS02.1-W200-DS37-00 is a digital AC servo drive controller manufactured by Bosch Rexroth Indramat as part of the DDS Drive Controllers series. Installed between a motion controller and a three-phase servo motor, it converts incoming supply power into a regulated output that follows commanded velocity and torque. In packaging lines, material-handling axes, and machining centers, the unit manages motor response, monitors feedback signals, and applies protective functions so the driven load follows programmed motion accurately. This control structure helps the axis maintain stable operation during acceleration, deceleration, and changing process loads.

Communication with higher-level control systems occurs through the SERCOS interface, a deterministic fiber-optic bus that transports setpoints and diagnostic data in real time. The power stage is rated for a continuous output of 200 A, allowing it to drive medium-to-large servo motors without derating. Thermal energy is removed by internal air cooling, which draws cabinet air across the heat sink instead of relying on external blowers. Contact protection complies with IP20, so the controller must be installed in a closed panel. Reliable operation is specified for ambient temperatures from 0 – 45 °C, a range suited to most production floors and test stands.

Full current capacity is available up to an elevation of 1000 m, so standard facilities at moderate altitudes need no compensation factors. Closed-loop accuracy is supported by an integrated digital servo feedback channel that sends high-resolution position data directly to the drive. During storage or shipment, the unit can withstand ambient temperatures from -30 – 85 °C. The controller is part of Line 02, which matches the mechanical and electrical arrangement used with compatible DDS supply modules, axis cards, and SERCOS fiber harnesses.
