Check the error referring to the following examples and take necessary
counter-measures:

ity flag. The RAM data abnormality flag in the status data
means that an abnormality has occurred. The flag will be
reset after it is read.
Example 2:
Always monitor the set values. Any value different from the
one that has been written means that abnormality has oc-
curred.
