KDA 3.3-050-3-DY0-U1

The Bosch Rexroth Indramat KDA 3.3-050-3-DY0-U1 from the KDA Spindle Drives series is a high-performance spindle drive designed for demanding CNC and automation applications. Manufactured by Bosch Rexroth Indramat, this drive delivers a rated current of 50 A and operates with a DC Bus Voltage of 300 V, ensuring robust continuous power for main spindle operations. The unit employs a Design 3 topology and is classified under Product: KDA, delivering precise positioning features and a wide, continuous speed range. Its Speed Command Value: Digital 16-Bit Parallel interface enables rapid, accurate speed adjustments for high stiffness and dynamic control.

Robust cooling is provided by a forced-cooled heatsink blower powered by an AC Supply Source for Heatsink Blower of 115 VAC, maintaining optimal thermal performance under heavy loads. The drive accepts an Auxiliary Encoder Input with Auxiliary and Synchronous Inputs (Due to AS 35 and Speed Command Value = A) for feedback redundancy, while an Aux. Interface: Without configuration simplifies integration where auxiliary ports are unnecessary. As part of the Series 3 family, it adheres to consistent mechanical and electrical footprints, facilitating straightforward replacement and system scaling.

Engineered for reliability, the KDA 3.3-050-3-DY0-U1 incorporates advanced monitoring and protective functions to safeguard against overcurrent and thermal overload. Its compact form factor and standardized mounting provisions streamline installation into machine tool cabinets. This spindle drive exemplifies the precision, durability, and speed control demanded by modern machining centers.
