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 Goodrive350-19 series VFDs 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.

Short-circuit
capacity
According to the definition in IEC 60439-1, the maximum allowable short-circuit
current at the incoming end is 100 kA. Therefore, the VFD is applicable to
scenarios where the transmitted current in the circuit is no larger than 100 kA
when the VFD runs at the maximum rated voltage.
Frequency
