Product Description:

The DDS03.1-W050-DS56-00-FW is a drive module manufactured by Bosch Rexroth Indramat for the DDS Drive Controllers series. It installs in a control cabinet and forms part of a modular motion package that converts fixed-frequency mains power into regulated pulses for servomotor torque, speed, and position control. By executing closed-loop commands issued from a higher-level controller, the unit coordinates axes in automated machining centers, printing lines, and material-handling cells where quick response and repeatable accuracy are required. This arrangement allows the drive to regulate motor behavior directly at the axis while supporting precise motion in multi-axis equipment.

This controller exchanges real-time motion data over a SERCOS interface, allowing deterministic communication with PLCs and other drives on the ring. The power section is rated for a continuous output of 50 A, so paired motors can accelerate rapidly without current starvation. Heat produced by the IGBT bridge is removed through internal air cooling, and cabinet airflow passes directly across the heat sink without requiring an external blower on the drive itself. Rotor position is returned through digital servo feedback, enabling high-resolution velocity and torque loops without analog drift. The unit is part of Line 03, which keeps it matched with compatible supplies and backplane components in the same series.

The hardware is Version 1, indicating the revision used for this controller. The product is a digital AC servo drive controller intended for operation with synchronous and asynchronous motors. Its output stage uses sinusoidal PWM outputs to supply regulated motor current, supporting stable speed control and responsive positioning during acceleration, steady-speed operation, and stopping phases. This control method helps reduce torque ripple and keeps motor response consistent across changing loads.
