KDA 2.1-100-3-LPD-W1

The Bosch Rexroth Indramat KDA 2.1-100-3-LPD-W1 from the KDA Spindle Drives series combines precision engineering with robust performance. This main spindle drive delivers a Rated Current of 100 A and operates on a DC Bus Voltage of 300 V, ensuring consistent power delivery across a wide speed range. Speed commands are handled via the high-speed SERCOS - Interface for real-time control, while the unit’s forced cooling by heatsink blower maintains optimal thermal conditions under heavy loads. Built for demanding manufacturing environments, the drive’s high stiffness and advanced positioning features support tight tolerance machining and rapid direction changes.

The drive’s auxiliary systems enhance integration and feedback capabilities. An Aux. Encoder Input provides spindle or secondary motor feedback, and a Position Command Value Digital 16-Bit Parallel Aux. Interface delivers precise position commands with minimal latency. The heatsink blower draws power from a 220 VAC AC Supply Source, enabling sustained cooling without compromise. With a compact Design 1 enclosure and the proven KDA Product architecture, the unit offers straightforward mounting and consistent mechanical footprints. Identified as Series 2, this model aligns with existing KDA components for seamless upgrades and maintenance.

Engineered for high-speed spindle applications, the KDA 2.1-100-3-LPD-W1 excels in milling, drilling, and grinding operations where accuracy and uptime are critical. The forced cooling system and robust electrical interfaces simplify commissioning and reduce downtime. For machine tool builders and end users seeking a dependable spindle drive solution with advanced digital communication and reliable thermal management, this KDA drive delivers industry-leading performance.
