KDA 3.3-050-3-LY0-W1

KDA 3.3-050-3-LY0-W1, Bosch Rexroth Indramat, KDA Spindle Drives defines a versatile main spindle drive optimized for demanding CNC and machine tool applications. This drive combines high stiffness construction with advanced positioning features to deliver precise spindle control over an extensive speed range. It features a Rated Current of 50 A and a robust DC Bus Voltage of 300 V, ensuring ample power headroom for continuous machining cycles. The unit’s design integrates a Speed Command Value via SERCOS - Interface for high-speed, deterministic communication and real-time feedback.

Engineered with operational reliability in mind, the drive employs a Forced Cooled by Heatsink Blower scheme powered by an AC Supply Source for Heatsink Blower: 220 VAC, eliminating thermal throttling under peak loads. Auxiliary inputs include an Aux. Encoder Input with Auxiliary and Synchronous Inputs (Due to AS 35 and Speed Command Value = A), enabling precise motion synchronization with external encoders. The Aux. Interface: Without option streamlines the control cabinet layout by removing superfluous ports. As a Design 3 Product in the Series 3, this KDA module offers native compatibility with Bosch Rexroth motor types and expansion units, simplifying system integration and reducing commissioning time.

Integration of the KDA 3.3-050-3-LY0-W1 into multi-axis machining platforms delivers not only dependable performance but also scalability across varied production setups. Its forced-air cooling and rugged construction guarantee consistent operation in high-duty cycles, and the SERCOS interface ensures seamless interoperability with standard motion controllers. Ultimately, this spindle drive delivers the reliability, flexibility, and precision essential for modern manufacturing environments.
