KDA 2.1-100-3-L00-U1

The Bosch Rexroth Indramat KDA 2.1-100-3-L00-U1 from the KDA Spindle Drives series combines precision engineering and robust performance in one compact package. This main spindle drive delivers a Rated Current of 100 A and operates at a DC Bus Voltage of 300 V to ensure continuous power and dynamic response across a wide speed range. Designed to interface seamlessly via a Speed Command Value: SERCOS - Interface, the drive incorporates high stiffness and advanced positioning features for demanding machining applications. Its forced cooling system, accomplished through a Heatsink Blower, maintains optimal thermal conditions even under prolonged high-load operation.

Precision and reliability are built in with a dedicated AC Supply Source for Heatsink Blower: 115 VAC that powers the cooling assembly independently of the main bus. The drive’s architecture follows Design 1 configuration guidelines and employs the flagship Product: KDA platform, ensuring consistency across installations. Auxiliary connectivity is streamlined, with both Aux. Encoder Input: Without and Aux. Interface: Without simplifying wiring and reducing potential failure points. Rated for Series 2 performance, the unit excels in CNC spindles, rotating tables, and high-speed indexing systems that demand rapid acceleration and deceleration.

Installation and maintenance are optimized for shop-floor efficiency: a modular footprint aligns with industry-standard mounting, and the forced-cooled heatsink blower is serviceable without full system disassembly. Built-in protection mechanisms guard against thermal overload and bus voltage excursions, safeguarding both the drive and the spindle motor. With its blend of continuous power delivery, precise speed control, and streamlined I/O, the KDA 2.1-100-3-L00-U1 spindle drive represents a technically advanced solution for high-precision metalworking and composite machining environments.
