APPENDIX 1.2 Release of self-diagnosis error

The CPU can perform the release operation for errors only when the errors allow the
CPU to continue its operation.
To release the errors, follow the steps shown below.
(1) Eliminate the error cause.
(2) Store the error code to be released in the special register D9060.
(3) Turn the special relay M9060 off to on.
(4) The target error is released.
After the CPU is reset by the release of error, the special relays, special registers and
LEDs for the error are returned to the states under which the error occurred.
If the same error occurs again after the release of the error, it will be registered again.
