When does the cooling fan run in the ATV71 drives?

Below is ATV61/71 Fan Control Strategy based on Frame Sizes:

Frame Size                                Control Strategy
2, 3, 4, 5a, 5b           The fan runs when drive thermal is greater than or equal to 70% and turns off when drive thermal is less than 60%.

6, 7a, 7b, 8                                The fans runs when the run command is given or when the drive thermal is greater than or equal to 70% and turns off when the drive thermal is less than 60% and runs for 1 minute after the run command is removed.

9, 10, 11, 12, 13, 14, 15           The fans runs when the run command is given or when the drive thermal is greater than or equal to 70% and turns off when the drive thermal is less than 60% and runs for 10 minutes after the run command is removed.

Here are some values regarding the drive thermal state (tHd) level and the temperature. The values are not linear.
tHd       =    Temperature
60 %    =    50?C
70 %    =    60?C
90 %    =    80?C
118 %  =   100?C
