What this drive is on the panel
The LXM18MESU60N4X: It ships without an integrated EMC filter, which matters for the cabinet builder: an external line filter sized for the 16 A three-phase input has to be specified separately to meet conducted-emissions class on the machine.
Power envelope and what 6 kW actually switches
Nominal power is 6.0 kW at 380...440 V three phase with a switching frequency of 8 kHz, so the drive is sized for mid-range servomotor loads — typical machine-tool spindles, packaging indexers, and converting-line web drives sit inside this rating band. Continuous output current is 20.8 A at 8 kHz and the 3-second peak is 55 A, meaning the drive handles roughly a 2.6× overload burst for accel/decel transients before the current foldback kicks in — dimension the motor's peak torque demand against that 55 A ceiling, not the continuous figure. Line current draw is 16 A at 380...440 V three phase, and the supply tolerance runs 342...484 V on a 50/60 Hz ±5 % network (47.5...63 Hz actual), so the drive rides through generator-fed sites and lightly regulated industrial feeds without tripping on undervoltage.
Fieldbus, safety, and cabinet environment
EtherCAT is integrated on-board — no option-card slot to populate for the fieldbus slice, which keeps the bill of materials flat for machine builders standardising on EtherCAT motion. Operating ambient is 0...45 °C up to 1000 m altitude with an IP20 rating, so the drive lives inside a sealed enclosure rather than on the machine frame; above 1000 m the standard servo-drive derating curve applies to the continuous output current. STO (safe torque off) is integrated per the catalog description, which lets the safety circuit cut drive output without removing the bus supply — the typical hard-wired safety-stop architecture for a Category 3 / PL d guard.
