Product Description:

The DDS02.2-A200-BE24-02-FW belongs to the DDS Drive Controllers series from Bosch Rexroth Indramat. It is installed in multi-axis automation racks where it acts as the power stage that converts DC-bus energy into regulated three-phase output for servo motors. By responding to velocity or position commands from a higher-level controller, the unit adjusts motor current to maintain precise speed, torque, and positioning in packaging lines, handling robots, or machine tools. This approach supports coordinated axis movement and reduces the need for separate analog control hardware.

Electrical capacity centers on a rated output of 200 A, allowing the drive to energize large continuous-duty servo motors without current derating. Thermal management relies on air cooling from outside the cabinet, so installation must provide a clear ventilation path that draws ambient shop air across the heat-sink fins before exhausting it. Command and diagnostic telegrams are exchanged over the SERCOS interface, which standardizes fiber-optic communication timing between the controller and the motion coordinator. For position verification, the unit accepts digital servo feedback, supporting high-resolution encoder signals for tight loop bandwidths. This combination lets the drive correct motion error in real time while maintaining synchronized communication with the control system.

The feedback channels also handle resolver feedback, giving the system a low-resolution signal that remains reliable at high temperatures or during rapid acceleration. Model coding shows that the unit is built in Line 02 and is released as Version 2. The unit is a Digital AC Servo Drive Controller that manages commutation, phase balancing, and fault monitoring during operation. It works as the motion power stage for compact machine cabinets where several axes share a common control structure and require consistent electrical response from the drive electronics.
