8-1-3 Operation Errors
After the parameters have been set, an operation error will occur if there is an invalid
setting or a contradiction between two parameter settings.
It won’t be possible to start the Inverter until the parameters have been set correctly.
(The minor fault output and fault contact output will not operate, either.)
When
an operation error has occurred, refer to the following table to identify and correct
the cause of the errors.
