Power delivery and current capability at the switching frequency
The LXM18PDU20M3X: Rated 2 kW nominal power at 220-240 V three-phase with an 8 kHz switching frequency, this drive delivers 18.5 A continuous output current at that carrier rate. The 3-second peak output current of 42 A supports the inrush needed for accelerating a load from standstill — roughly 2.3× the continuous rating, which is typical for servo drives handling high-inertia loads like rotary tables or unwinders. Line current draw is 13.2 A at 220-240 V three-phase, so the upstream branch circuit and contactor must be sized for that continuous draw plus the peak transient.
Supply voltage tolerance and frequency range
Operates on a three-phase 220-240 V supply with a -15% / +10% tolerance window (170-255 V), which covers the typical European and Asian low-voltage industrial networks. Supply frequency acceptance is 50-60 Hz ±5%, with the internal network frequency range extending to 47.5-63 Hz — adequate for generator-backed or weak-grid installations where frequency can drift.
Communication and I/O architecture
The drive integrates Modbus serial communication alongside digital and analog I/O, plus PTI (pulse train input) and PTO (pulse train output) for direct connection to a motion controller or PLC without an external interface module. Two analog inputs are available for speed or torque reference signals from a potentiometer or analog output card.
Environmental limits and derating
Rated for ambient air temperatures from -5°C to 45°C — above 45°C the drive must be derated or actively cooled; the 0-1000 m altitude limit means no derating is needed at most industrial sites, but installations above 1000 m require a power reduction per IEC 61800-2.
EMC filter consideration
This variant ships without an integrated EMC filter, so an external filter must be added at the input to meet conducted emission limits for CE or UKCA compliance — factor the filter cost and panel space into the BOM.
