KDA 3.1-050-3-A00-U1

KDA 3.1-050-3-A00-U1, Bosch Rexroth Indramat, KDA Spindle Drives delivers precise spindle control in a robust, industry-proven package. This drive features high torsional stiffness, advanced positioning capabilities, and an extensive speed range with continuous power output optimized for demanding machining operations. The unit supports a Speed Command Value of Analog +/- 10V input for seamless integration with standard controller architectures. Forced cooling via an integrated heatsink blower ensures stable thermal performance during peak load cycles.

Built for rigorous industrial environments, the drive is engineered with a Rated Current of 50 A and a DC Bus Voltage of 300 V to sustain constant torque under heavy cutting conditions. Its forced-cooling system operates on a dedicated AC Supply Source for Heatsink Blower: 115 VAC to maintain optimal semiconductor junction temperatures. The module’s electrical interfaces are streamlined: Aux. Encoder Input: Without and Aux. Interface: Without minimize wiring complexity when encoder or I/O expansion is not required. As a Design 1 product in the Product: KDA family, Series 3 units benefit from a compact footprint and simplified mounting, reducing cabinet space by up to 20%. Conformal-coated power sections and precision-wound inductors ensure low electrical noise and high electromagnetic compatibility.

Engineers will appreciate the drive’s plug-and-play compatibility with Bosch Rexroth CNC systems, accelerating commissioning and parameter cloning across multiple axes. Its reliable thermal management and sine-shaped current output protect both spindle bearings and cutting tools, extending maintenance intervals and uptime. Ideal for high-precision milling, turning, and grinding centers, the KDA 3.1-050-3-A00-U1 drive optimizes throughput while maintaining the stringent quality standards of modern manufacturing.
