When output frequency is less than 5 Hz, the carrier frequency is 2
kHz; When output frequency is 5...10 Hz, the carrier frequency is 4
kHz; When output frequency is more than 10 Hz, the carrier frequen-
cy is the same as customer's setting.
For derating figures related to carrier frequency, see
To achieve optimized performance, the carrier frequency setting
should follow the equation: [C0.05] ≥ 10 x [E0.08].
With [C0.06] = 1, the carrier frequency can also be changed automatically to
keep the power module temperature within the normal range.
With [C0.06] = 2, the carrier frequency is always fixed to C0.05.
