KDA 2.1-100-3-DYD-W1

The KDA 2.1-100-3-DYD-W1, Bosch Rexroth Indramat, KDA Spindle Drives main spindle drive delivers precision and high dynamics in a compact package. Engineered for demanding machining and milling applications, it provides robust stiffness and rapid response across an extensive speed range. Integrated digital controls ensure seamless communication with upstream PLCs and motion controllers. The drive’s architecture supports continuous operation under heavy loads while maintaining tight positioning accuracy.

The drive’s key specifications include a Rated current of 100 A fed by a DC bus voltage of 300 V for high torque output. Cooling is managed by a Forced air by heatsink blower system, driven by an AC supply for heatsink blower of 220 VAC to maintain optimal thermal conditions. Both the Position command interface and the Speed command interface utilize a Digital 16-bit parallel format, while the encoder feedback accepts both Auxiliary and synchronous inputs for advanced motion synchronization. The unit is designated as Model KDA, Series 2, Design 1, reflecting its second-generation architecture with enhanced reliability.

Designed for straightforward integration, the KDA 2.1-100-3-DYD-W1 installs directly into standard drive racks with minimal adaptation. Its forced-cooling heatsink blower and rugged construction ensure high uptime even in harsh industrial environments. Together with Rexroth’s configuration tools, this spindle drive offers engineers reliable performance, rapid commissioning, and extended maintenance intervals for high-volume production systems.
