Product Description:

The DDS02.2-W100-BE45-01-FW is a digital AC servo drive controller from Bosch Rexroth Indramat in the DDS Drive Controllers series. It mounts in an Indramat drive rack and controls three-phase synchronous or asynchronous motors used in machine tools, packaging lines, and material-handling axes. By converting bus power into controlled output phases and exchanging position data with a CNC or PLC, the unit supports closed-loop motion for dynamic positioning, stable speed regulation, and coordinated multi-axis operation. The controller serves as the link between the shared DC bus and the motor, regulating current so the axis can respond accurately to changing load conditions during acceleration, deceleration, and steady running.

Communication with higher-level motion systems is handled through the SERCOS interface, which provides fiber-optic noise immunity and cycle-synchronous setpoint exchange. Thermal management uses internal air cooling, so cabinet airflow must move across the heat sink to carry away operating heat. A nominal output capability of 100 A allows the controller to operate medium-to-large servo motors without early current limiting in normal duty. For motor feedback, the unit accepts digital servo feedback for high-resolution encoder signals and resolver feedback for applications that need a rugged analog feedback option in areas with vibration or electrical interference.

The controller carries Function ID 01, which identifies its assigned function within the DDS platform. It is part of Line 02, and the electronics are listed as Version 2. These identifiers keep the drive aligned with the matching power supplies and expansion modules used for that product line, and they help distinguish this controller from other DDS configurations with different control features or feedback arrangements.
