Product Description:

The DDS03.1-W030-RA01-01 belongs to the DDS Drive Controllers series from Bosch Rexroth Indramat. It is a drive controller that manages torque, speed, and position for connected AC servo motors in industrial automation cells, packaging equipment, and material-handling axes. By processing motion commands from a higher-level PLC and adjusting its power stage accordingly, the unit forms the electrical link between the motion control system and the mechanical load. This arrangement allows commanded movement to be translated into controlled motor operation during indexing, feed, and positioning tasks across automated equipment.

The drive communicates with the machine control through an analog interface, allowing voltage or current references to set velocity or torque commands without a digital fieldbus. Heat generated by the power electronics is removed through internal air cooling, with cabinet air moving across the heat sink so no external ducting is required. The power stage is rated for a continuous output of 30 A, which lets the controller operate medium-frame servo motors through their normal duty cycle. Rotor position is returned to the drive as resolver feedback, allowing sinusoidal commutation and stable speed regulation without a separate encoder channel. This feedback method also helps the controller maintain accurate motor control in applications that require dependable closed-loop performance during repeated motion cycles.

The unit is a Digital AC Servo Drive Controller. It is part of Line 03 and uses Function ID 01 with Version 1. These identifiers set the controller's assigned configuration within the DDS platform and keep parameter handling consistent for this model. In multi-axis cabinets, this helps the module remain matched to the intended control structure and operating behavior of the surrounding system, while preserving clear integration with other DDS components already used in the same installation.
