Product Description:

The DDS03.1-W030-RA01-00 is a servo drive controller in the DDS Drive Controllers series produced by Bosch Rexroth Indramat. It is installed inside multi-axis control cabinets to modulate power delivered to an attached electric motor in automated machinery. In operation, it serves as the electrical link between the cabinet power section and the motor, converting commanded values into regulated output current. The unit coordinates speed, torque, and position loops based on feedback so the connected axis follows commands from the higher-level control system. This type of control is commonly used where precise motion must be maintained during acceleration, steady running, and stopping.

This model delivers a continuous output of 30 A. That is the maximum motor phase current the drive can supply without exceeding its thermal limits during continuous operation. Command data enter through the analog interface, allowing the higher-level controller to set velocity or torque with proportional voltage signals. Rotor position is returned through resolver feedback, and the absolute angle signal lets the drive maintain commutation and motion control across the speed range. Thermal energy is removed by internal cabinet air cooling, so cabinet airflow must be maintained to prevent derating. The controller is part of Line 03 in the DDS product range.

The unit carries Function ID 01 and is built as Version 1. It is classified as a Digital AC Servo Drive Controller, and it exchanges phase-leg measurements, fault status, and diagnostic data with the control system during operation. These signals allow the machine control to monitor operating conditions and react to faults without interrupting normal feedback processing. The drive is intended for closed-loop servo applications that require accurate current regulation and continuous position evaluation. Its standardized coding and cooling arrangement within the DDS range keep the unit consistent with other compatible cabinet-based servo components.
