Product Description:

The DDS02.1-W025-DS11-01 drive controller is manufactured by Bosch Rexroth Indramat within the DDS Drive Controllers series. Installed inside a control cabinet, it links a plant’s motion CPU with the power stage that feeds a synchronous or asynchronous servo motor. By shaping phase current and monitoring feedback in real time, the unit supports precise velocity and torque regulation required in assembly stations, printing lines, and material-handling axes. This role lets the drive respond quickly to changing loads during acceleration, deceleration, and steady-state operation.

At its output, the controller supplies a continuous load of 25 A, which is the maximum motor current that can be maintained without overheating. Command and diagnostic data move through the SERCOS interface, a deterministic fiber-optic bus that synchronizes multiple axes with consistent timing. Rotor position returns through digital servo feedback, allowing the internal regulator to correct error during each control cycle and maintain stable closed-loop control. Heat is removed by internal air cooling, so cabinet airflow must pass across the heat sink rather than rely on an external blower mounted on the module. Operating logic is tied to Function ID version 01, which keeps the controller within the intended parameter range for this function group.

The unit is part of Line 02 and is built as Version 1, which places it within a specific product generation of the series. It is classified as a Digital AC Servo Drive Controller, so it serves as the regulating stage between the control system and the motor in a multi-axis cabinet. Built-in diagnostic functions report temperature status, overcurrent events, and bus-state information to the supervising PLC, allowing faults to be detected early and operating status to remain visible during machine operation. These status messages help the control system respond to abnormal conditions before they develop into longer interruptions.
