KDA 3.2-100-3-LYS-U1
KDA Spindle Drives
The Bosch Rexroth Indramat KDA 3.2-100-3-LYS-U1 belongs to the KDA Spindle Drives series and combines Digital control technology with an Indramat KDA series drive type for superior precision and reliability. Designed as a single axis solution, this cabinet-mount unit employs an Internal (LYS) cooling method to maintain thermal stability across demanding industrial environments. With a robust design capable of continuous operation from 0 °C up to +45 °C, the drive seamlessly integrates into automated systems requiring synchronized spindle control. An IP10 protection class rating safeguards internal electronics when installed within appropriate enclosures.
The drive delivers a rated output current of 100A and accepts a 3-phase 230/400V AC supply at 50/60 Hz, ensuring compatibility with global power standards. A dedicated 300 V DC bus voltage backbone powers the spindle motor with minimal ripple, while the unit’s compact footprint supports straightforward cabinet mounting. Weighing approximately 16-20 kg, the KDA 3.2-100-3-LYS-U1 balances rigidity and manageable mass for secure installation. The combination of high-frequency switching and a front-mounted heatsink fan ensures the rated current delivers consistent torque under prolonged duty cycles.
Connectivity is enhanced by a versatile U1 signal interface offering both analog/digital inputs and an industry-standard SERCOS speed command value link for real-time data exchange. Advanced resolver and sine-cosine feedback compatibility enables high-accuracy position and speed control, with auxiliary encoder inputs for expanded axis synchronization under AS 35 protocols. A supplementary RS-232C port facilitates firmware updates, parameter tuning, and diagnostic communication with host controllers or PC-based tools. The result is an industrial-grade spindle drive engineered for demanding automation tasks in machining, grinding, and mill-turn applications.
