Error Classification and Confirmation
Section 9-1
CPU Unit Indicators and Error Meanings in RUN or MONITOR Mode
Seven-segment Display
Error codes are shown on the 7-segment display if an error occurs. The 7-
segment display has only two digits, so 4-digit error codes are displayed two
digits at a time. If there are 4-digit error details in addition to the error code,
they will be displayed after the error code two digits at a time.
• Display Example
Error code: 80F1 (memory error)
Error details: 0001 (user program)
The display switches at intervals of approximately 1 s.
• If two or more errors occur at the same time, the most serious error will be
displayed first. When that error is cleared, the next most serious error will
be displayed.
• The 7-segment display shows digits created by special instructions in the
user program or by analog adjustment operations. Error code displays,
however, are given priority whenever an error occurs.
