Hi all
I have a problem.
6SE7031-OTE60-Z Siemens simovert masterdrives
The inverter turns the message my F023 and see how the fan inverter does not work so display this message. Take away the fan and see that no problem. I handed him exterior 220v AC and ventilate the inverter. Knows someone what to see;;;;

Thank you.

good morning

The problem may be related to CUVC who is reading wrong values of temperature and / or board sources who were not able to close the relay to turn on the fan .. one day .. check all connections can be bad contact
