0.4 kW at 8 kHz — the rating that governs the real load
The LXM18PDU04M2X delivers 0.4 kW nominal power at 220-240 V single phase with an 8 kHz switching frequency. Continuous output current is 2.8 A at that switching rate; the 3-second peak output current is 9.6 A, which covers the acceleration transient for a motor load sized to the continuous rating. The switching frequency is fixed at 8 kHz — not a carrier that can be lowered to gain more continuous current, so the 2.8 A figure is the hard thermal limit for sustained duty. Line current draw is 4.9 A at 184.65 % of the nominal load under single-phase 220-240 V supply. That percentage tells you the drive draws nearly double its rated output current from the line during peak demand — budget the upstream branch circuit protection and wiring for at least 5 A continuous per drive, not the 0.4 kW output number.
Single-phase supply — voltage window and frequency tolerance
Rated supply voltage is 220-240 V single phase with a -15 to +10 % tolerance, giving a working range of 170-255 V. The supply frequency acceptance band is 50-60 Hz ±5 %, and the network frequency tolerance extends to 47.5-63 Hz. That covers most global single-phase mains, but the lower voltage end (170 V) will reduce the available output torque — the drive can't boost the DC bus beyond what the input rectifier sees. No integrated EMC filter is fitted. For CE-marked installations or any panel that must pass radiated/conducted emissions testing, budget for a filter rated to the 4.9 A line current.
Compact housing — panel fit and thermal constraints
The drive measures 155.5 mm wide by 48.0 mm high by 166.5 mm deep. That's a low-profile footprint for a 0.4 kW servo — it fits in a shallow 200 mm-deep enclosure with room for wiring ducts. The IP20 rating means it's intended for cabinet installation only; no washdown or dust protection. Operating ambient temperature range is -5 to 45 °C. In a sealed cabinet with other heat sources, the internal temperature rise above ambient needs to stay below that ceiling. The 8 kHz switching stage dissipates heat proportional to the output current; derating is required above 45 °C, though the datasheet doesn't publish the curve here — plan for forced ventilation if the cabinet ambient exceeds 40 °C.
Integrated I/O and communication — what's on the connector
The drive carries Modbus, digital I/O, analog I/O, PTI (pulse train input), and PTO (pulse train output) all integrated — no option cards needed for basic motion control. Two analog inputs are available for speed or torque reference from a PLC or potentiometer. The PTI/PTO channels handle step-and-direction or encoder follower applications up to the drive's internal pulse rate.
