4.5 kW at 220 V — sizing the motor pair
The LXM23AU45M3X: Rated 4.5 kW continuous power at 220 V three-phase input, with a continuous output current of 32.5 A. That current figure is the one to match against the motor's rated current at the drive's switching frequency — the drive's I²t limit, not the power label, governs the thermal headroom for the application. Supply voltage tolerance is -20…15 % on the 220 V nominal, so it accepts 170…255 V three-phase without a transformer tap change.
Book format and altitude derating — panel fit
Book format means the drive mounts with the wide face vertical, stacking side-by-side on the backplate. For a retrofit into an existing Lexium 23 cabinet, the footprint matches the original cutout and DIN-rail clip positions — no need to re-drill the subplate. Rated for installation up to 1000 m altitude without derating. Above that, continuous power drops 1 % per 100 m — at 2000 m the drive delivers roughly 90 % of its 4.5 kW rating. Factor this into the motor torque budget if the cabinet sits at elevation.
CAN interface and leakage current — integration notes
The drive communicates via CAN — the Lexium 23 Plus family uses CANopen DS-402 for motion control. If the existing line runs CAN, this drive drops into the network without a gateway. Maximum leakage current to earth is 3.5 mA, which is low enough that a standard 30 mA RCD on the supply will not nuisance-trip unless multiple drives share the same residual-current device.
