KDA 3.3-050-3-LYS-U1

KDA 3.3-050-3-LYS-U1, Bosch Rexroth Indramat, KDA Spindle Drives is a high-performance main spindle drive designed for precision machining applications. This drive delivers robust performance with its optimized power stage and advanced control interfaces. Its compact footprint and modular design simplify integration into existing CNC platforms. The KDA 3.3-050-3-LYS-U1 ensures reliable operation under continuous load conditions, making it ideal for demanding industrial environments.

Incorporating a DC Bus Voltage: 300 V rail and a continuous Rated Current: 50 A output, this spindle drive maintains consistent torque across a wide speed range. Forced cooling via a heatsink blower powered by an AC Supply Source for Heatsink Blower: 115 VAC keeps thermal levels in check during intensive cycles. The unit supports a Speed Command Value: SERCOS - Interface, providing deterministic, high-speed communication over fiber-optic bus systems. Auxiliary functions include Aux. Encoder Input: With Auxiliary and Synchronous Inputs (Due to AS 35 and Speed Command Value = A) for precise position feedback, and Aux. Interface: Serial Interface RS 232 C for configuration and diagnostics. Engineered in a sturdy Design: 3 industrial housing, this drive belongs to the proven Product: KDA line and the third Series: 3 iteration of Rexroth’s spindle solutions.

Seamless integration with SERCOS-based motion networks accelerates commissioning and streamlines multi-axis synchronization. The forced-cooling scheme and robust electrical design enhance reliability, minimizing unplanned downtime in high-volume production. Ideal for high-stiffness spindle applications in machining centers, the KDA 3.3-050-3-LYS-U1 delivers precise speed control, exceptional rigidity, and long-term operational stability.
