KDA 3.1-100-3-LQI-U1

Product Description:

The KDA 3.1-100-3-LQI-U1 servo drive comes from Bosch Rexroth Indramat and sits inside their KDA Spindle Drives family. This model shows up ready to push torque in axis motion jobs, bringing a rated current of 100 A for plenty of pull. Fit for machine tools or milling spindles, it operates with a nominal frequency of 50/60 Hz and needs 3x230/400 V AC on the line. Setup is usually for one axis, and it can manage tight feedback and rapid reversals, since spindle drives don’t get to rest with production expecting zero delays.

Cool enough to run inside the tight control panel, this version uses internal airflow—no outside ducts, no fuss about contamination, just internal (I) cooling that works inside its own shell. It stays protected thanks to IP20 class, so accidental contact is blocked and dust levels stay managed. Electronic brains inside stick with LQI (Linear Quadratic Integral) control—the fine tuning means accuracy, whether speeding up a tool head in machining or sliding hydroelectric machinery into the right alignment. For talking to the rest of the system, it links in with the SERCOS interface, which is standard now in lots of linked automation lines.

Panel wiring goes to a U1 power connection, and mounting lets it tuck next to drives from the same product group. Housing sheds heat through its frame with no loud fans, which suits installs trying to cut noise or airborne dirt. In places where spindle changes happen often or settings swap between automated parts, the KDA brings tight response and steady output, day or night. Good for cells where digital axis control makes the real difference in downtime and scrap reduction. Minimal maintenance if voltages hold steady, and swapping these drives usually takes less time because of the familiar connections and controls. Reliable drive, no drama.
