Product Description:

The DDS02.1-A050-DS03-01 is a digital AC servo drive controller produced by Bosch Rexroth Indramat for modular multi-axis motion systems. Installed beside matching power supplies in rack assemblies, the unit converts regulated DC bus energy into controlled output for servo motors. It governs three-phase motor windings through closed-loop current and velocity control so axes can follow commanded motion accurately in packaging lines, assembly equipment, and material-handling systems. Its housing width matches other DDS modules, which helps maintain compact rack layouts.

Communication with the automation system is handled through the SERCOS interface, allowing cyclic setpoints, status words, and diagnostic data to travel over a fiber-optic ring at deterministic intervals. A continuous output current of 50 A allows the drive to operate medium-frame servo motors without thermal derating under normal conditions. Thermal management uses external air cooling, so fresh ambient air moves through the heat sink instead of recirculated cabinet air. For rotor position and commutation, the controller processes digital servo feedback signals, allowing closed-loop operation without separate Hall tracks. The product is part of Line 02 in the series.

The unit carries Function ID 01, which identifies its assigned function class within the platform. It is built in Version 1, indicating the revision used for this drive type. Bosch Rexroth Indramat lists the model in the DDS Drive Controllers series, where it is intended for coordinated servo applications with compatible rack components. The controller stores operating parameters internally, and its connector layout supports straightforward integration with adjacent DDS modules. This arrangement supports synchronized axis control in systems that use modular power supplies and centralized motion commands.
