The KDA 2.1-050-3-D00-W1, Bosch Rexroth Indramat, KDA Spindle Drives main spindle drive excels in delivering high mechanical stiffness and precision positioning across a wide speed range. Its robust control architecture integrates seamless digital velocity feedback for accurate speed tracking and torque management. Engineered for demanding CNC machine tools, the unit maintains consistent continuous power even under rapid load fluctuations. Compact and modular, it simplifies installation and future scalability within automated production cells.
Designed around a high-voltage DC link, this drive operates on a DC Bus Voltage of 300 V and provides a continuous Rated Current of 50 A, supporting sustained spindle acceleration. Heat rejection is handled by forced cooling via an integrated heatsink blower, drawing power from a dedicated AC Supply Source for Heatsink Blower at 220 VAC. Speed setpoints are issued through a robust Speed Command Value interface with Digital 16-Bit Parallel resolution, ensuring sub-microsecond update rates. For system simplicity, the unit omits both Aux. Encoder Input: Without and Aux. Interface: Without options, and conforms to Design class 1 within the Series 2 classification for streamlined selection.
This spindle drive’s forced-air cooling and digital control loop deliver exceptional reliability and low thermal drift over extended runtimes. Integration into Bosch Rexroth automation ecosystems is facilitated by standardized mounting dimensions and a unified parameter database, reducing commissioning time. Ideal for high-precision machining, milling, and grinding applications, the KDA 2.1-050-3-D00-W1 ensures consistent performance and uptime in the most challenging production environments.
