For pulse frequencies in the range between the fixed values, the relevant derating factors
can be determined by means of linear interpolation.
The following formula applies for this:
Example:
The derating factor is required for when X
2
= 2 kHz for 6SL3710-7LE41-0AA0.
X
0
= 1.25 kHz, Y
0
= 100%, X
1
= 2.5 kHz, Y
1
= 87%, X
2
= 2 kHz, Y
2
= ??
