Product Description:

The DDS02.1-W050-RS04-03-FW is a digital AC servo drive controller produced by Bosch Rexroth Indramat within the DDS Drive Controllers series. Designed for multi-axis automation, the device regulates torque, speed, and position when paired with compatible motors. It is part of Line 02 and uses Version 1 hardware for this platform. In a coordinated machine system, the controller converts motion commands from higher-level PLCs into precise current output for packaging, printing, and material-handling applications. It provides the regulated motor current needed for controlled acceleration, stable speed control, and repeatable positioning during continuous operation.

Motion data reach the unit over the SERCOS interface, a fiber-optic real-time bus used for fast cyclic communication between the controller and the motion system. The power stage can deliver a continuous output of 50 A, which is suitable for medium-frame servomotors in coordinated axes. Thermal losses are removed by internal air cooling, so airflow inside the control cabinet must remain unobstructed during operation. Rotor position is returned through resolver feedback, providing the signals needed for closed-loop motor control. The controller has an IP20 housing, so it must be installed in a closed electrical cabinet where it is protected from dust, moisture, and direct contact.

Operation is permitted in ambient temperatures from 0 to 45 °C, allowing the controller to share cabinet space with other heat-generating equipment when ventilation is adequate. Installations can reach elevations of up to 1000 m above sea level before derating is required. During storage or transport, the unit withstands temperatures from -30 to 85 °C without damage to electronic components. The operating range applies while the drive is powered, while the wider storage range covers non-operating conditions during shipping or warehousing. These limits should be observed so the controller remains within its intended electrical and thermal range.
