Product Description:

The DDS03.1-W030-DS04-00 is a digital AC servo drive controller manufactured by Bosch Rexroth Indramat within the DDS Drive Controllers series. It conditions three-phase power, processes command words, and modulates current so that connected servo motors follow precise torque, speed, and position references generated by CNCs or PLCs. By housing the power stage, logic, and communication hardware in a single module, the unit acts as the bridge between industrial control software and mechanical motion in automated assembly lines, packaging machinery, and material-handling gantries. This arrangement lets one cabinet-mounted controller manage both power conversion and closed-loop motion tasks without requiring separate external control electronics.

Deterministic communication is provided through the SERCOS interface, allowing synchronized setpoint exchange and diagnostic reporting on a fiber-optic ring. Heat is removed by internal air cooling that pulls cabinet air across the heat sink, eliminating external ducting. The enclosure carries an IP20 protection category, so it must be mounted in a closed electrical cabinet. A continuous output capability of 30 A supports medium-power axes such as feed drives and tool changers. Reliable electronic operation is permitted between 0–45 °C, and the controller uses digital servo feedback to maintain stable velocity and position regulation during dynamic load changes.

Site conditions require installation at or below 1000 m to preserve cooling performance and electrical spacing. During transport or warehouse storage, the unit withstands ambient extremes from -30–85 °C without component damage. It belongs to Line 03, which indicates its power class and plug-in module compatibility. The controller is released as Version 1, identifying the first product revision in this design. These operating limits are relevant when the drive is mounted in compact control cabinets alongside other heat-generating automation equipment.
