Product Description:

The DDS02.1-W150-DS31-00 is a digital AC servo drive controller built by Bosch Rexroth Indramat for the DDS Drive Controllers series. The unit acts as the power and control interface between a supply module and an AC servo motor, executing torque and speed commands from higher-level motion processors. In automated machinery, it modulates motor phases with pulse-width-modulated voltage so closed-loop axes hold commanded position and velocity. Its modular format supports installation in multi-axis drive cabinets that use a shared DC bus.

The controller exchanges real-time setpoint and diagnostic data through the SERCOS interface, allowing deterministic communication over a fiber-optic ring. Thermal management relies on internal air cooling, so cabinet air moves across the heat sink instead of requiring an external blower. The power stage supplies a continuous output of 150 A, which supports medium-to-large synchronous motors in the W rating group. Component spacing and conductor clearances meet IP20, so live parts are finger-safe, but the unit must be installed inside a closed panel. Reliable operation is permitted between 0–45 °C, and higher cabinet temperatures require additional ventilation. The device belongs to line 02 of the platform.

Position feedback is processed through digital servo feedback, allowing the controller to close current and velocity loops with single-connector wiring. Installation altitude is permitted up to 1000 m above sea level, and output current must be reduced above that height. Long-term storage temperatures range from -30 to +85 °C, which helps protect the electronic assemblies during shipment and storage. The unit is Version 1, indicating the first revision of this model. This version information should be considered when matching existing parameter sets to the drive.
