‹Operator Programming Errors

An Operator Programming Error (OPE) occurs when two or more parameter related to each other are set inappropriately or an individual parameter setting is incorrect. The Inverter does not operate until the parameter setting is corrected; however, no other alarm or fault output will occur. If an OPE occurs, change the related parameter by checking the cause shown in the table below. When an OPE error is displayed, press the ENTER key to see U1-34 (OPE Detected). This monitor displays the parameter that is causing the OPE error.
