Goodrive350-19 Series VFD for Crane
When the altitude exceeds 1000m, derate by 1% for every increase of 100m. When the altitude
exceeds 3000m, consult the local INVT dealer INVT office for details.
B.2.2.3 Derating due to carrier frequency
The VFDs in different power classes are different in carrier frequency. The rated power of a VFD 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
AC 3PH 380V(-15%) – 440V(+10%)
Grid voltage
AC 3PH 520V(-15%) – 690V(+10%)
According to the definition in IEC 61439-1, the maximum allowable short-circuit
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 100kA when
