Cause : Multi-Power module drive interconnection cable error comes when the Inter-connect trip indicates a multi-power module drive interconnection cable error.

1. The sub-trip "xx.0.00" indicates which power module has detected the fault where xx is the power module number.
2. It should be noted that this trip is also initiated if the communication fails either when a rectifier signals a fault or a trip is reset.
3. In this case, the sub-trip is the number of modules that are still communicating correctly.
