Product Description:

The DDS02.1-W100-RS53-02-FW belongs to the DDS Drive Controllers series manufactured by Bosch Rexroth Indramat. It is a digital drive controller that coordinates servo axes in automated machinery, converting setpoint commands from a motion control system into regulated motor current and voltage for precise speed and position control. By integrating into the DDS modular rack, the unit provides compact axis control for packaging lines, handling robots, material-processing stations, and other equipment that depends on coordinated motion.

This controller communicates with the host CNC or PLC through a SERCOS interface, allowing fiber-optic, real-time cyclic data exchange for speed, torque, status, and command values. During operation it can deliver up to 100 A of continuous output current, so the connected servo motor receives sustained drive current without external amplification. Thermal management relies on internal cabinet air cooling; the heat sink uses the cabinet airflow rather than a separate fan mounted on the module. Motor position is returned to the drive through resolver feedback, giving rotor angle information for closed-loop regulation across the speed range. Functionally, the unit is a Digital AC Servo Drive Controller, so current control, protective limits, and diagnostic functions are handled by internal electronics.

The hardware is identified as Line 02, and design Version 1 marks the first revision of that line. Integrated diagnostic LEDs and an error memory provide direct status indication and support fault review during operation. Parameter cloning through the communication link allows matching axes in the same machine to receive the same settings without manual reentry, which helps keep multi-axis setups consistent. The controller fits the DDS rack format, so it can be installed with companion modules in a compact drive assembly.
