What the 4.5 kW rating means for the motor match
The LXM26DU45M3X is a 4.5 kW servo drive at 220 V three-phase, switching at 8 kHz — that's the nominal motor power it's designed to drive continuously without exceeding the thermal limits of the output stage. Continuous output current is 22.9 A at that same 8 kHz switching frequency, so the drive delivers full rated torque into a motor with that current draw at the nameplate voltage. For short bursts during acceleration or deceleration, the drive can push 61 A for 3 seconds — useful for overcoming inertia on a rapid index move without oversizing the drive for the steady-state load.
Line current and upstream protection sizing
Line current at 220 V three-phase is 17.9 A at 147.1 % of rated load — that's the draw the branch circuit breaker and supply cables need to be rated for, not the motor's continuous current. Supply voltage limits are 170…255 V three-phase, 50/60 Hz ±5 %, with the network frequency window at 47.5…63 Hz — the drive tolerates a wider frequency swing than the voltage tolerance allows. Overvoltage category III means this drive is designed for fixed installation downstream of the building's main distribution board, where transient overvoltages are already clamped by upstream SPDs.
Altitude derating and installation limits
Above 1000 m the output voltage derates at 1 % per 100 m — at 2000 m the drive loses 10 % of its output voltage capability, which directly reduces the available torque at the motor shaft. Maximum leakage current is 1.55 mA — below the 3.5 mA threshold that would require a fixed RCD or a dedicated earth leakage warning label per IEC 60364.
