KDA 3.1-100-3-DYS-U1

The Bosch Rexroth Indramat KDA 3.1-100-3-DYS-U1 from the KDA Spindle Drives series delivers precision spindle control with a rated current of 100 A and a DC Bus Voltage of 300 V. This Product KDA main spindle drive is part of the Series 3 lineup and features a 16-bit digital parallel Speed Command Value for high-resolution velocity control in advanced machining operations. Housed in a compact Design 1 enclosure, the drive maintains continuous power output across an extensive speed range while offering advanced positioning capabilities with minimal torsional deflection. Robust mechanical construction ensures high stiffness and stability under dynamic loads, making it ideal for demanding CNC applications.

Thermal management is assured by forced cooling by heatsink blower and an onboard blower powered by a 115 VAC AC Supply for Heatsink Blower, maintaining optimal junction temperatures during peak workloads. Communication interfaces include an RS-232C serial Auxiliary Interface for parameterization and diagnostics plus auxiliary & synchronous inputs on the Aux Encoder Input port for precise feedback integration. The drive's modular architecture provides standardized mounting points and plug-and-play connectors, reducing system commissioning time, and it supports seamless integration with Rexroth control software. Comprehensive protective functions guard against overcurrent, overvoltage, and thermal overload, while built-in diagnostic routines monitor drive health and log operational data to extend service life in industrial environments.

Engineered for high stiffness, dynamic accuracy, and refined speed control, the KDA 3.1-100-3-DYS-U1 excels in spindle, grinding, and milling applications requiring tight tolerances. Its high current capacity, advanced cooling design, and extensive interface options make it an essential component in modern CNC machining centers and rotary indexing systems. With its blend of precision, reliability, and ease of integration, this spindle drive ensures maximum uptime and performance in production-critical environments.
