= High overloadability current. Allows +50% load variation. 50% exceeding can be continuous.
All values with cosϕ = 0.83 and efficiency = 97%.

NX Liquid-Cooled drive electrical output power.
If the motor is continuously (besides start and stop ramps) run at frequencies below 5 Hz, pay attention to the
drive dimensioning for low frequencies, i.e. maximum I

or choose drive according to I
H
. It is
recommended to check the rating with your nearest distributor.
Drive overrating may also be necessary if the process requires high starting torque.
The voltage classes for the inverter units used in the tables above have been defined as follows:
Input 540 VDC = Rectified 400 VAC supply
Input 675 VDC = Rectified 500 VAC supply
The enclosure class of all inverter units is IP00.
