Product Description:

The DDS03.1-W050-R is a digital AC servo drive controller built by Bosch Rexroth Indramat for the DDS Drive Controllers series. Installed inside a control cabinet, it channels power and control signals to matched servo motors so automated axes can hold commanded speed, torque, and position in real time. The unit serves as the link between a PLC motion processor and the electromechanical load, allowing coordinated closed-loop movement in production lines, pick-and-place stations, and material-handling systems. Because the drive regulates motor operation continuously, it helps the machine respond quickly to changing loads and programmed motion sequences.

The drive delivers a continuous output of 50 A, which is the continuous RMS current available to the connected motor without thermal derating of the power electronics. Its cooling method is internal air cooling, so cabinet air moves through an integrated heat sink and no external ducting is required. The enclosure is rated IP20, which supports installation in protected electrical cabinets while reducing the risk of accidental contact with live parts. Motor position is read by resolver feedback, providing analog shaft position signals that resist electrical noise in industrial environments. Reliable operation is permitted at ambient temperatures from 0 to 45 °C, allowing stable output during normal machine operation when cabinet ventilation is adequate.

The controller belongs to Line 03 and is version 1. These identifiers place it within an established DDS configuration and support compatibility with related cabinet components in the same product line. Installation sites may be located up to 1000 m above sea level without additional cooling allowances. When offline, the unit can withstand storage conditions from -30 to 85 °C, which supports transport and warehouse storage before installation or reuse.
