6.5.7 Operating
Frequency (uF.11)
The operating frequency, with which the power modules are clocked, can be changed
depending on the application. The maximum possible operating frequency as well as
the factory setting is defined by the used power circuit. Influence and effect of the
operating frequency are listed in the following table:
low operating frequency
- less inverter heating
- less discharge current
- less switching losses
- less radio interferences
- improved concentricity at small
speeds
high operating frequency
- less noise development
- improved sine-wave simulation
- less motor losses
