Power Unit Settings
In this menu, you can change the settings of the fan and the sine filter.
The fan operates in the optimized or the always on mode. In the optimized mode, the internal logic of the drive
receives data about the temperature and controls the fan speed. After the drive goes in the Ready state, the fan
stops in 5 minutes. In the always on mode, the fan operates in full speed, and does not stop.
The Sine filter keeps the overmodulation depth in limits and does not let the thermal management functions
decrease the switching frequency.
