Product Description:

The DDS03.1-W050-DS04-02 is a Digital AC Servo Drive Controller built by Bosch Rexroth Indramat for the DDS Drive Controllers series. Intended for cabinet integration, the controller converts DC-link energy into three-phase output for matched servo motors while monitoring current and velocity loops. In automated packaging cells, gantry loaders, and printing lines, it provides the regulated motion profiles required by PLC or CNC hosts. Precise modulation of the power devices inside the unit supports tight position control, short response times, and coordinated multi-axis operation across distributed machine sections.

The drive supplies up to 50 A of continuous output, so the connected motor can accelerate heavy loads without derating the controller. An enclosure grade of IP20 indicates finger-safe construction for installation inside a protected electrical cabinet. Allowed ambient operation spans 0 to 45 °C, covering most conditioned shop floors while still requiring cabinet ventilation when internal heat sources are dense. Thermal energy is removed through internal air cooling, which means the unit draws cabinet air across its heat sink rather than relying on external ducting. Command and diagnostic data flow over a SERCOS interface, providing deterministic fiber-optic communication for cycle-synchronous motion commands and parameter exchange.

Drive-to-motor position verification relies on digital servo feedback, allowing the controller to close the velocity and position loops with very fast updates. Installation altitude can reach 1000 m without special cooling measures, which suits machinery placed on elevated floors or at moderate mountain sites. When powered down, the electronics tolerate storage conditions between -30 to 85 °C, helping protect modules during transport or spare-part storage. Product identification places the controller in line 03 and version 1, matching the same DDS generation used in multi-axis racks.
