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
Grid voltage
AC 3PH 380V (-15%)
–440V (+10%)
AC 3PH 520V (-15%)
–690V (+10%)
Short-circuit capacity
According to the definition in IEC 61439-1, 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
50/60 Hz±5%, with a maximum change rate of 20%/s

B.4.1 EMC compatibility and motor cable length
The following table describes the maximum motor cable lengths that meet the requirements of the EU
EMC directive (2014/30/EU).

You can learn the maximum length of the motor cable through the running parameters of the VFD. To
understand the accurate maximum cable length for using an external EMC filter, contact the local
INVT office.
For description about the environments category II (C3), see section B.6 EMC regulations.
