700202: Rotational speed monitoring defective

Hello ,

I bought the Gildemeister CTX420 V6 machine with Sinumerik 840D powerline and after switching it on for the first time the error occurs:

700202: Rotational speed monitoring defective

and we can't turn on the machine. The instructions say that after turning on the machine, speed monitoring will also be turned on.

Of course we still have a lot of errors. We may have fixed the rod replenishment and what's left is still there.

Attachment 502253

We still have to buy the cooling system tomorrow and feel the tank, but that won't erase all the errors, right? Strangely, the error "Chip conveyor: Overfull" comes up even though there is no coolant in it.

Error 700202 worries us.

Some temporary help? What errors prevent us from starting the machine?

Thanks in advance.

Best regards

Igor
