KDA 2.1-100-3-A0I-U1

KDA 2.1-100-3-A0I-U1, Bosch Rexroth Indramat, KDA Spindle Drives offers a high-performance solution for demanding machining applications. The drive delivers a continuous Rated Current of 100 A and harnesses a DC Bus Voltage of 300 V to enable broad speed regulation and torque-density. Engineered for rigidity and dynamic responsiveness, it features embedded positioning functions and a wide constant-power range to accommodate both heavy-duty and precision operations. This main spindle drive excels in providing consistent spindle acceleration while maintaining tight speed control under varying loads.

Incorporating a dedicated AC Supply Source for Heatsink Blower rated at 115 VAC, the unit employs a Forced Cooled by Heatsink Blower scheme to ensure stable thermal management even during prolonged cycles. The drive's Speed Command Value interface supports Analog +/- 10V inputs for seamless integration with standard CNC control loops. An Aux. Interface with Incremental Encoder Output delivers real-time feedback for closed-loop synchronization, while the Aux. Encoder Input is provisioned as "Without" to simplify wiring when external encoders are not required. The design architecture (Design: 1, Series: 2) reflects Bosch Rexroth Indramat's modular approach, enabling straightforward retrofit into existing KDA frameworks.

Seamless integration into multi-axis machining centers is facilitated by the drive's compact footprint and standardized connector layout, reducing installation time. The robust forced-cooling system and conservative thermal allowances enhance reliability, minimizing unplanned downtime. With high stiffness characteristics and precise positioning capabilities, the KDA 2.1-100-3-A0I-U1 spindle drive is ideally suited for applications ranging from high-speed milling to heavy turning operations, delivering consistent performance and long-term operational stability.
