Product Description:

The DDS02.1-A050-DS01-02-FW is a drive controller manufactured by Bosch Rexroth Indramat for the DDS Drive Controllers series. Installed in industrial cabinets, it receives motion commands from a supervisory PLC and modulates the output stages that energize matched servo motors during coordinated machine movement. The device sits on the common DDS rack, shares a DC bus with adjacent modules, and closes the torque, velocity, and position loops required for packaging equipment, transfer lines, and CNC machinery. By translating bus data into regulated motor current, it helps protect mechanical assemblies while keeping cycle times consistent across multi-axis stations.

The controller exchanges cyclic setpoints and diagnostic data over a SERCOS interface, allowing deterministic fiber-optic networking with other drives and sensors in the motion system. Under normal duty, it can deliver up to 50 A of continuous output, a rating that limits the motor size it can actuate without derating. Rotor position is returned through digital servo feedback; this signal lets the microprocessor adjust PWM patterns in microseconds for tight speed control and accurate position regulation. Thermal management relies on external air cooling, so ambient air is pulled from outside the cabinet to remove switching losses and keep heat sink temperatures below design limits. Application-specific parameters are supplied through a separate firmware order so the drive can be matched to the required control functions.

The unit carries Function ID 01, linking it to preconfigured control algorithms used in this drive class. It is part of hardware line 02, which corresponds to the second generation of the power electronics used in the platform. The release status is Version 1, indicating the first production release for this configuration. The product category, Digital AC Servo Drive Controller, means the module handles closed-loop current regulation and PWM generation internally, leaving only high-level motion profiles to the central controller.
