I have a doubt about the conversion between hp and kW, especially in the high range power

The figures in the catalogue (and on the drives plate, etc...) are not a conversion from kW to HP :

Example : ATV61HC31N4 : 315 kW / 500 HP
You can do the conversion :
315 kW = 427 HP and
500 HP = 369 kW.
The reason is : this size can drive 500 HP motors (in you are in the USA, motor powers are expressed in HP) and 315 kW motors (if you are in Europe). In fact this drive accept motors to 369 kW.

This is because motor sizes are standard and for big sizes there is not equivalent motors in HP and in kW.
The drive available maximum power is the biggest figure converted in the correct unit.
