FPΣSelf - Diagnostic and Troubleshooting12 - 6Procedure 2:For error code is 1 to 9Condition: There is a syntax error in the program.Operation 1Change to PROG. mode and clear the error.Operation 2Execute a total - check function using FPWIN GR to determine the location of thesyntax error.For error code is 20 or higherCondition: A self-diagnostic error other than a syntax error has occurred.OperationUse the programming tool “FPWIN GR” in PROG. mode to clear the error.Using FPWIN GRClick on the “Clear Error” button in the “Status display dialog box”. Error code 43 andhigher can be cleared.In the PROG. mode, the power supply can be turned off and then on again to clearthe error, but all of the contents of the operation memory except hold type data arecleared.An error can also be cleared by executing a self-diagnostic error set instruction F148(ERR).If the mode selector switch has been set to the ”RUN” position, the error is clearedand at the same time operation is enabled. If the problem that caused the error hasnot been eliminated, it may look in some cases as though the error has not beencleared.When an operation error (error code 45) occurs, the address at which the error oc-curred is stored in special data registers DT90017 and DT90018. If this happens,click on the “Operation Err” button in the “Status display dialog box” and confirmthe address at which the error occurred before cancelling the error.Tip
