Sizing the drive to the motor load
The LXM18MESU75N4X is a motion servo drive in the Easy Lexium 18 range, rated at 7.5 kW nominal output across the 380...440 V three-phase input window — the headline figure that sizes the motor and the upstream branch protection together, because line current at the same envelope is 21 A.
Input envelope and cabinet integration
Supply voltage limits are 342...484 V three phase at 47.5...63 Hz, so the drive accepts a 50 Hz or 60 Hz plant feed without reconfiguration; operating altitude is capped at 0...1000 m and ambient 0...45 °C — above 1000 m the continuous output current must be derated per the published curve.
Fieldbus slice and safety wiring
EtherCAT is integrated on the unit, so the controller slice communicates motion setpoints over the standard fieldbus without an extra option card — for a packaging line or converting machine this keeps the motion axis on the same network as the rest of the I/O, simplifying the rack layout. Safe Torque Off (STO) is part of the device short name LXM18M designation carried in the catalogue entry, giving the safety circuit a hardware-only path to remove drive torque without cutting main power — the wiring approach that lets a Cat 3 / PL d stop function ride on a single safety input pair.
Lifecycle and BOM position
CE is the compliance mark carried in the spec row;.
