KDA 3.1-050-3-L0I-W1

KDA 3.1-050-3-L0I-W1, Bosch Rexroth Indramat, KDA Spindle Drives is a high-performance main spindle drive engineered for precision applications requiring wide speed ranges and robust continuous power delivery. The unit delivers exceptional stiffness and dynamic response, combining advanced position-control algorithms with a compact, modular design. Integrated diagnostics monitor drive health and protect critical functions, while the rugged construction withstands demanding industrial environments. Featuring a seamless digital interface, this drive supports rapid commissioning and real-time feedback to optimize machine throughput.

Incorporating a Rated Current of 50 A and a DC Bus Voltage of 300 V, the drive ensures stable torque output across the entire speed envelope. Thermal management is provided via Cooling by a dedicated heatsink blower, powered from a AC Supply Source for Heatsink Blower of 220 VAC to maintain optimal junction temperatures under heavy duty cycles. Speed reference is handled through a Speed Command Value via a SERCOS - Interface, while position feedback pathways rely on an Aux. Interface supporting incremental encoder signals. The drive’s electrical topology reflects the proven Design "1" architecture from the Product family, within Series "3", enabling consistent performance and straightforward integration. Note that there is no Aux. Encoder Input, simplifying the wiring harness and reducing potential points of failure.

Engineers will appreciate the drive’s plug-and-play compatibility with existing SERCOS networks and the forced-cooling arrangement that cuts maintenance intervals. The precise speed and position control fosters higher throughput in milling, turning, and grinding operations, elevating machine tool productivity. With Bosch Rexroth Indramat’s reputation for reliability and support, the KDA 3.1-050-3-L0I-W1 offers a compelling solution for modern manufacturing lines seeking consistent, high-fidelity spindle control.
