Product Description:

The KDA 2.1-100-3-D0I-U1 is an advanced multi-axis spindle drive from the KDA Series 2 lineup. Bosch Rexroth designs it specifically for intricate manufacturing systems that need coordinated three-axis control. This cabinet-mounted drive unit shines in high-tech machining centers, multi-spindle turning tasks, and synchronized manufacturing processes. Its capability in providing precise multi-axis coordination is crucial for high quality production results. With its Design type 1 construction and dimensions of 330mm x 310mm x 300mm, the drive offers impressive control capabilities while fitting comfortably into standard control cabinets. Its mass of 25 kg ensures sound mechanical integrity for demanding industrial settings.

The KDA 2.1-100-3-D0I-U1 is engineered to operate with digital current control technology. It manages spindle operations with precision through advanced electronic regulation algorithms. This ensures reliable performance even under varying operational demands. The 100 A continuous output current provides ample power for multi-axis applications while keeping power efficiency high during long production runs. The drive is compatible with various electrical setups and can function optimally with a three-phase input between 380 to 460V AC. This ensures support for both local and international power systems without the need for voltage conversion equipment. The integrated 300V DC bus voltage guarantees optimal power conversion efficiency and stable operation, even under dynamic load conditions.

The drive is designed to support encoder feedback which enhances precision in spindle operation. This also allows it to adapt to various system requirements for seamless performance. The drive is capable of enabling real-time coordination between multiple drive units and master control systems. This is facilitated by SERCOS communication support that provides high-speed data exchange capacity for advanced system coordination. This unit is built for durability and comes with low maintenance requirements. It is also warranty protected and comes with a one year Wake Industrial warranty.
