The Bosch Rexroth Indramat KDA 2.1-100-3-DPI-W1 is a robust main spindle drive from the KDA Spindle Drives series by Bosch Rexroth Indramat. This drive features a Rated Current of 100 A and a DC Bus Voltage of 300 V, delivering continuous power over a wide speed range. Its high stiffness and precision positioning capabilities make it ideal for demanding spindle applications in machining centers and precision tooling operations. Designed for seamless integration, the KDA 2.1-100-3-DPI-W1 ensures reliable performance in environments requiring dynamic speed control and constant torque.
In-depth technical specifications highlight the drive’s advanced architecture. The heat sink blower is powered via an AC Supply Source for Heatsink Blower of 220 VAC, providing forced cooling that maintains optimal operating temperatures under heavy loads. Speed references are handled through a Digital 16-Bit Parallel Speed Command Value, enabling high-resolution speed control and rapid response to setpoint changes. Feedback is managed by an Aux. Encoder Input configured for spindle or second motor feedback, while the Aux. Interface offers an incremental encoder output for synchronization with CNC controllers. This combination of digital command and precision feedback ensures accurate speed regulation and torque delivery throughout the operating range.
Additional features emphasize compatibility and reliability in industrial environments. The forced cooling system reduces thermal stress and extends component life, while the auxiliary encoder interface supports integration with a variety of feedback devices for enhanced system diagnostics. The drive’s modular design and standardized digital interface facilitate straightforward installation and maintenance. Although no external certifications are specified, the KDA 2.1-100-3-DPI-W1 meets Bosch Rexroth Indramat’s rigorous internal quality standards. In industrial applications, this spindle drive delivers improved machining accuracy, reduced downtime, and superior process efficiency, making it a valuable asset for high-precision manufacturing.
