Operator Programming Errors

An Operator Programming Error (OPE) occurs when an inapplicable parameter is set or an individual param-
eter setting is inappropriate. The Inverter will not operate until the parameter is set correctly; however, no
alarm or fault outputs will occur. If an OPE occurs, change the appropriate parameter by checking the cause
shown in Table 7.3. When OPE error is displayed, press the ENTER key to display U1-34 (OPE Detected).
This monitor will display the parameter that is causing the OPE error.
