KDA 2.1-050-3-AP0-U1

The KDA 2.1-050-3-AP0-U1, Bosch Rexroth Indramat, KDA Spindle Drives main spindle drive delivers precision motion control with robust dynamics and a broad speed range. Designed for high-stiffness applications, it provides seamless spindle acceleration and deceleration while maintaining positioning accuracy under varying loads. Its compact form factor integrates easily into both retrofit and new-build machining centers, ensuring quick installation and minimal footprint impact. Certified to industry standards, this drive meets demanding requirements for repeatability and cycle consistency across diverse machining tasks.

The drive’s core performance is defined by a continuous Rated Current of 50 A and a DC Bus Voltage of 300 V, enabling high torque output and stable DC link operation. Speed regulation is achieved via an Analog +/- 10V Speed Command Value, while the Aux. Encoder Input accommodates both spindle and secondary motor feedback for dual-loop control. Forced heat dissipation is provided by a dedicated Cooling system through a Heatsink Blower powered from an AC Supply Source for Heatsink Blower of 115 VAC, ensuring thermal stability during extended cut cycles. The unit features a streamlined Design labeled as 1 within the Product family, and it belongs to Series 2, with no additional Aux. Interface modules required.

Integration into automated production lines is simplified by its plug-and-play connectivity and compatibility with standard motion controllers, reducing engineering overhead. The drive’s forced-cooling arrangement and rugged construction guarantee high reliability even in harsh manufacturing environments. Ideal for high-speed spindles, this KDA drive enhances throughput and process efficiency, making it a trusted solution for precision milling, grinding, and drilling applications.
