B.3 Grid Specifications - INVT Goodrive35 Series Operation Manual

Goodrive35 Series Closed-loop Vector Control VFD
When the altitude exceeds 2000m, configure an isolation transformer on the input end of the VFD.
When the altitude exceeds 3000m but is lower than 5000m, contact us for technical consultation. Do
not use the VFD at an altitude higher than 5000m.
B.2.2.3 Carrier frequency derating
The power of Goodrive350 series VFDs varies according to carrier frequencies. 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 380 V (-15%)–440 V (+10%)
Grid voltage AC 3PH 380 V (-10%)–550 V (+10%)
AC 3PH 520 V (-15%)–690 V (+10%)
According to the definition in IEC 60439-1, the maximum allowable short-circuit
Short-circuit current at the incoming end is 100 kA. Therefore, the VFD is applicable to
capacity scenarios where the transmitted current in the circuit is no larger than 100 kA
when the VFD runs at the maximum rated voltage.
Frequency 50/60 Hz±5%, with a maximum change rate of 20%/s
