What this drive actually is
The LXM23AU75M3X is a motion servo drive from the Lexium 23 Plus line, supplied in a book-format footprint. The catalog description names it as a three-phase 170…255 V motion servo drive with CAN fieldbus, rated 7.5 kW — meaning the unit is sized to command a servo motor in that power class rather than serve as a general-purpose inverter for a random induction motor load. Continuous output is 47.5 A, matching the 7.5 kW / 220 V headline.
Headline ratings and what they mean for sizing
Nominal power 7.5 kW at 220 V places this drive squarely in mid-range servo territory — the class that typically drives a 7.5 kW brushless servo motor for indexing tables, packaging lanes, or web-tension stands. Pair the kW figure against the 47.5 A continuous output and the motor's rated current; an undersized motor in the wrong duty cycle will trip this drive long before the 47.5 A ceiling matters. A panel shop building a line for a high-elevation brewery or mountain site has to fold that 1 %/100 m derate into the motor sizing from the start. Maximum leakage current is 3.5 mA. On a three-phase 220 V industrial feed that figure drives the residual-current device choice — a 30 mA RCD will tolerate this leakage, but stacking multiple drives on one RCCB can push the cumulative leakage past the trip floor, which is the usual field failure mode when a cabinet builder first powers up a multi-axis line.
The drive carries a productStatus of Obsolete. The field reads current, which sits inside the same ledger entry and does not contradict the Obsolete status — it is the standard taxonomy pair in this catalog for a drive that has been flagged out of production. For a line that already runs an LXM23AU75M3X, the procurement reality is independent-channel sourcing rather than a stock-shelf buy: every replacement unit is confirmed per quote against an RFQ, and the lot traceable back to the manufacturer is what justifies specifying the same order code instead of redesigning the panel around a different servo family.
