Product Description:
The DDS02.1-W050-DS31-00 is a drive controller produced by Bosch Rexroth Indramat within the DDS Drive Controllers series. As a Version 1 controller, it forms part of a modular drive stack used to run synchronous and asynchronous servo motors in cabinet-based systems. The unit receives a stabilized DC bus from a shared power supply and modulates it to a three-phase output that follows velocity or position commands, allowing coordinated multi-axis motion in packaging lines, material-handling gantries, and general factory automation. This arrangement lets the controller respond to rapid current changes during acceleration, deceleration, and synchronized axis movement.
It delivers a continuous output current of 50 A, giving the drive enough headroom for medium-torque axes without oversizing the power section. Command and diagnostic data move over a fiber-optic SERCOS interface, which provides deterministic cycle times for tightly synchronized machinery. The enclosure carries an IP20 protection category, so it must be mounted inside a closed control cabinet. Heat is removed by air from inside the control cabinet, so the cabinet layout must maintain adequate airflow paths. Safe operation is specified for ambient temperatures between 0 to 45 °C. These operating conditions cover electrical loading, network communication, enclosure placement, and thermal planning for the axis.
Position control accuracy is supported by digital servo feedback, enabling high-resolution encoder data to close the loop at the drive rather than at the PLC. The unit can be installed up to 1000 m above sea level without performance derating, which suits most plant elevations. During transport or storage, it withstands temperatures from -30 to 85 °C, allowing shipment and warehousing in unconditioned spaces. The controller is part of Line 02 in the DDS platform, and this line uses the corresponding housing dimensions and connector arrangement for the series. That layout supports cabinet integration in coordinated multi-axis systems.
