Rating envelope and what it switches
The LXM15HC20N4X sits in the Lexium 15 motion servo drive line at a nominal 42.5 kW three-phase, drawing 60.6 A line current at 208 V three phase and 60.9 A at 480 V three phase on the supply side, with an apparent-power figure of 50 kVA. On the motor side the continuous output current is 70 A three phase, the peak output current is 198 A three phase, and the transient RMS output current is 140 A for 5 s three phase — meaning the drive handles the cyclic torque peaks typical of a servo axis without tripping into the overload foldback during normal acceleration. Supply tolerance is 208…480 V - 10…10 % (limits 187.2…528 V) at 50/60 Hz - 5…5 % (47.5…63 Hz), three phase, which covers the common industrial plant rails on either side of 400 V without an external transformer.
Motor cable reach and switching behaviour
Output voltage is rated for cable runs of 1000…2000 m with derating of the motor output current by 1.5 % per additional 100 m, so a long cable run to a remotely mounted servo motor costs real torque headroom rather than just wire. The switching frequency of 8 kHz is the carrier setting that sets the audible motor whine and the switching losses in the output stage; running the drive above that point is not a parameter the user adjusts on this model. The unit ships without an EMC filter, so cabinet-side filtering (line filter + correct cable shielding and bonding) carries the conducted-emissions budget for any CE-marked machine build. Earthing compatibility covers TN, TT, and IT with an additional isolation transformer on the power supply, which is the configuration a TN-S plant typically uses and what an IT-distribution site needs to add for safe operation of the drive.
Lifecycle status and the supply route that remains
The LXM15HC20N4X is recorded as obsolete on the manufacturer's record, so new production is not the channel — the unit moves through independent distribution as service and replacement stock for installed Lexium 15 axes. For a tail-spend buyer the practical move is to fold any service-quantity need onto a controlled preferred-supplier channel against an RFQ so the order sits in the same procurement workflow as the rest of the Lexium spares rather than as a one-off requisition.
