Technical Principles and Innovative Values

Innovation Point 1:High Current Capacity with Precise Control

The REXROTH DDS2.1W200-D​incorporates advanced power electronics technology,delivering 200A peak current while maintaining precise control accuracy.The drive utilizes high-frequency PWM modulation with switching frequencies up to 16kHz,ensuring smooth torque output and minimal current ripple.This allows the drive to handle high-inertia loads and rapid acceleration/deceleration cycles without compromising positioning accuracy.

Innovation Point 2:Modular Architecture with Plug-in Cards

Unlike conventional fixed-function drives,the DDS2.1W200-D​features a modular design that supports plug-in cards for customized functionality.This architecture enables users to add specific communication protocols,I/O interfaces,or special control functions without replacing the entire drive.The plug-in card system reduces inventory costs and allows for easy field upgrades as application requirements evolve.

Innovation Point 3:SERCOS Interface Integration

The drive integrates a high-speed SERCOS(Serial Real-time Communication System)interface,providing deterministic real-time communication with cycle times as low as 31.25 microseconds.This enables synchronized multi-axis control applications where precise coordination between multiple drives is essential.The SERCOS interface supports up to 254 nodes per network,making it suitable for large-scale automation systems.

Innovation Point 4:Advanced Thermal Management

The DDS2.1W200-D​employs a sophisticated thermal management system with temperature-controlled cooling and comprehensive thermal protection.The drive continuously monitors internal temperatures and automatically reduces output power when temperatures approach critical levels.This thermal protection system extends component life and prevents catastrophic failures in high-temperature industrial environments.

Application Cases and Industry Value

Case Study:Automotive Assembly Line

A major automotive manufacturer in Germany deployed the REXROTH DDS2.1W200-D​servo drives across their robotic assembly line for engine block machining operations.The application required precise positioning of heavy machining heads with positioning accuracy of±0.01mm and repeatability of±0.005mm.The previous servo drives struggled with thermal management during continuous 24/7 operation,requiring frequent maintenance and causing production delays.After switching to the DDS2.1W200-D​drives,the plant achieved 99.98%uptime over two years,with the drives’advanced thermal management system maintaining stable operation even during peak summer temperatures.The SERCOS interface enabled seamless integration with the existing CNC control system,reducing commissioning time by 50%and eliminating the need for additional interface modules.

Case Study:Packaging Machinery

A food packaging equipment manufacturer implemented the DDS2.1W200-D​drives in their high-speed form-fill-seal machines.The application required rapid acceleration and deceleration cycles to achieve packaging speeds of 200 packages per minute while maintaining precise web tension control.The drives’200A peak current capability allowed the machine to handle the high inertial loads during rapid direction changes,while the precise current control maintained consistent torque output for accurate web tension regulation.The modular design enabled the manufacturer to customize the drives with specific I/O cards for their proprietary control algorithms,reducing development time by 30%compared to off-the-shelf solutions.
