Cooling fan control
The cooling fan on a VFD67 size E is a dual speed fan and on size F, it is
a variable speed fan. The drive controls the speed at which the fan runs
based on the temperature of the drives heatsink and also the drive's
thermal model system.
See section 4.2 Heatsink fan on page 20.
