S120 : Fault 6500 : Infeed : Line synchronization not possible

I am commissioning new system with S120 drives : CU320-2 with smart line module and motor modules.
I get the fault 6500 : Infeed : Line synchronization not possible.
I have attached two pictures. The firs one shows some parameters concerning the fault.
The second one measured line frequency.
Connections of the power seems ok, so, what could be the reason for this fault?

Please check the value of p0211 & confirm it matches to your supply line frequency, e.g. if value set is = 60 Hz & your supply frequency is 50 Hz, fault would triggered. If it is OK with your supply voltage frequency, try by replacing infeed module.

HTH.
