KDA 2.1-050-3-API-U1

KDA 2.1-050-3-API-U1, Bosch Rexroth Indramat, KDA Spindle Drives brings robust performance to high-precision machining centers. Engineered for spindle applications, it provides exceptional stiffness and dynamic response across an extensive speed range. The drive’s positioning features and continuous power output make it ideal for demanding CNC spindles and milling spindles. Integrated monitoring and protective functions secure smooth, uninterrupted operation under variable loads.

At its core, this unit delivers a Rated Current of 50 A and a DC Bus Voltage of 300 V, ensuring ample energy for high-torque starts. The AC Supply Source for Heatsink Blower is powered at 115 VAC, which drives the Cooling system via a forced-cooling heatsink blower to maintain optimal thermal conditions. Speed commands are accepted through a Speed Command Value of Analog +/- 10 V, and feedback loops leverage the Aux. Encoder Input with support for spindle or second motor signals. An Aux. Interface provides an incremental encoder output, facilitating precise speed and position tracking. Additional designations include Design «1», Product «KDA», and Series «2», reflecting its modular architecture and compatibility with Indramat automation ecosystems.

Engineers will appreciate the KDA’s seamless integration into existing Rexroth control networks, reducing commissioning time and wiring complexity. Its robust forced-cooling design and built-in encoder interfaces enhance long-term reliability and maintenance intervals. Ideal for high-speed spindles in milling, drilling, and grinding applications, the KDA 2.1-050-3-API-U1 ensures stable torque delivery and precise speed control in the most exacting manufacturing environments.
