Product Description:

The DDS02.1-A100-DS04-03-FW is a drive controller produced by Bosch Rexroth Indramat for the DDS Drive Controllers series. As an axis control module, it regulates power delivered from a DC bus to matched servo motors and supports closed-loop speed and torque control in automated machinery and material-handling lines. By converting command data from a motion controller into precise three-phase output, the unit links PLC-level instructions with electromechanical motion for coordinated positioning and repeatable cycle times. This operating role makes it suitable for transfer axes, packaging equipment, and other machines that depend on consistent motor response under changing loads.

Communication with higher-level devices is handled through the SERCOS interface, a fiber-optic fieldbus that carries cyclic setpoints, diagnostic data, and real-time status in a fixed telegram structure. Thermal management relies on external air cooling, so the installation must provide a clear airflow path across the heat sink fins. The controller delivers a continuous output of 100 A, which supports medium-to-large synchronous motors without current derating in normal operating conditions. Its housing has an IP20 rating, so it protects against finger contact but must be mounted inside a cabinet. Reliable operation is intended for ambient temperatures from 0 – 45 °C, which fits most indoor industrial environments with controlled ventilation.

Feedback from the motor is returned as digital servo feedback, which supports accurate position control and stable speed regulation. This feedback method also lets the drive process rotor position information directly inside the control loop for responsive acceleration and deceleration. For storage or transport, the unit tolerates temperatures from -30 – 85 °C when it is not energized. Operation is permitted up to 1000 m above sea level before cooling performance begins to decrease. The controller is part of Line 02 and Version 1.
