FPΣ
Self-Diagnostic and Troubleshooting
12 - 6
Procedure 2:
For error code is 1 to 9
Condition: There is a syntax error in the program.
Operation 1
Change to PROG. mode and clear the error.
Operation 2
Execute a total-check function using FPWIN GR to determine the location of the
syntax error.
For error code is 20 or higher
Condition: A self-diagnostic error other than a syntax error has occurred.
Operation
Use the programming tool “FPWIN GR” in PROG. mode to clear the error.
Using FPWIN GR
Click on the “Clear Error” button in the “Status display dialog box”. Error code43 and
higher can be cleared.
In the PROG. mode, the power supply can be turned off and then on again to clear
the error, but all of the contents of the operation memory except hold type data are
cleared.
Anerror can also be cleared byexecuting a self-diagnostic error set instruction F148
(ERR).
If the mode selector switch has been set to the ”RUN” position, the error is cleared
and at the same time operation is enabled. If the problem that caused the error has
not been eliminated, it may look in some cases as though the error has not been
cleared.
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 confirm
the address at which the error occurred before cancelling the error.
