6.3 Operation Errors
After the constants have been set, an operation error will occur if there is an invalid setting
or a contradiction between two constant settings.
It won't be possible to start the VS-656DC5 until the constants 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.
* By pressing the ENTER key when OPE02 appears, the setting error con-
stant is displayed on U1-50 as shown below.
