rated power. When the altitude exceeds 1000m, derate by 1% for every increase of 100m. When the
altitude exceeds 3000m, consult the local INVT dealer or local INVT office for details.
B.2.2.3. Derating due to carrier frequency
The power of the VFD varies according to carrier frequencies. The VFD rated power is defined based
on the carrier frequency set in factory. If the carrier frequency exceeds the factory setting, the power
of the VFD is derated by 10% for each increased 1 kHz.
B.3 Grid specifications
