Self diagnosis error
When the error of Motion CPU
occurs independently, set it in
the range of 10000 to 10999
according to the classification of
error in diagnosis error (SD0).
At this moment, self diagnosis
error flag (SM1) and diagnosis
error flag (SM0) are also ON.
Even if the error of PCPU occurs,
self diagnosis error will not occur.
Correct the program if necessary.
Motion error detection flag
(M2039)
No matter which error occurs,
M2039 will be ON in Motion
CPU. -
Depending on the type
of an error that
occurred, M2039 is
turned ON. (Only when
SFC is used)
Correct the program if necessary.
