POWER UNIT SETTINGS
In this menu, you can change the settings of the fan, the brake chopper, the sine filter, and
the harmonic filter.
The fan operates in the optimised or the always on mode. In the optimised 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.
The harmonic filter can be enabled to avoid possible resonances in the DC-link of the AC
drive.
