Cooling fan control
The cooling fan on a Commander SK size 2 is a dual speed fan and on
sizes 3 to 6, 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. The cooling fan on Commander
SK size 6 is a variable speed fan which requires an external +24Vdc
power supply.
See section 4.2 Heatsink fan on page 31.
