Product Description:

The DDS02.1-W150-DS55-00-FW is a digital AC servo drive controller produced by Bosch Rexroth Indramat within the DDS Drive Controllers series. It converts DC-link energy from the supply module into sinusoidal output that matches dynamic setpoints delivered by higher-level automation equipment. In industrial plants, the unit drives synchronous or asynchronous servomotors so that conveyor axes, tool heads, and feeders track precise motion commands without mechanical overshoot. Because the output is electronically regulated, the controller can support smooth acceleration, controlled deceleration, and repeatable speed behavior during changing process demands. It is commonly used in cabinet-based motion systems where several axes must respond predictably to centralized control commands.

The built-in SERCOS interface serves as the real-time fieldbus, and the paired communication interface ensures deterministic transfer of position words, parameter data, and diagnostic bits over fiber-optic rings. Continuous phase current is maintained up to 150 A, and this rated current allows the drive to energize large torque motors while supporting demanding acceleration cycles. Heat generated by switching devices is removed through internal air cooling, so cabinet airflow must move across the heat sink and no external ducts are required. Rotor position and speed are returned through digital servo feedback, allowing the drive to close its internal current and velocity loops with very fast updates. This control structure helps the axis respond quickly to load disturbances and maintain stable motion during frequent starts, stops, and reversals.

The controller uses separate firmware that is ordered and loaded separately, allowing application-specific feature sets without hardware changes. Application functions are therefore selected in software while the same power hardware remains in place. The unit is part of Line 02, which indicates the second-generation power stage layout used for this model. Its electronics are Version 1, which marks the initial board revision. This arrangement separates application selection from the basic power electronics and keeps the revision level clear.
