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

50/60 Hz±5%, with a maximum change rate of 20%/s
