When does the heatsink fan turn on an ATV320 drive?

Resolution:
By default, the Heatsink fan on the ATV320 drives will start automatically when the drive thermal state reaches 70%.
The behavior can be modified by adjusting the Fan Mode parameter setting in the drive.

The Parameter Fan Mode is found in under the Drive Menu - CONF - Full - SET and the code is FFM (on the local keypad an M looks like a tall n).
The section describing the Fan Mode parameter states:

Default setting is Standard (Std) but it could be modified to Always (run) or Never (StP).
If set to Always it will run when power is applied to the drive.
If set to Always, the fan may need to be replaced sooner than the 3-5 years listed in the installation manual.

If set to Never it will never run the fan.
If set to Never the max ambient temp is limited to 40 deg C and the service life of the drive is reduced.
We do not recommend this selection.
