When errors which do not turn off the shut-off signal occurs in the safety observation
function, the safety observation warning flag (SM24) turns ON and the error code
(SD32) and detail code (SD33) are stored. Release the alarm depending on contents
of error codes.
The errors other than with (Note-1, Note-3, Note-5) cannot be reset. Restart the
system (power supply ON or reset of PLC CPU) after release of errors.
In addition, when the safety observation warnings occur, a self-diagnostic error flag
(SM1) and diagnostic error flag (SM0) turn ON, and a self-diagnostic errors (error code
10051) is stored in diagnostic errors (SD0).
Table 6.2 Safety observation warning list
Error cause
The source data in the BCD instruction is
other than 0 to 9999.
Each digit of the source data in the BIN
instruction is other than 0 to 9.
The device points in the BMOV instruction
is outside the range.
The device points in the FMOV instruction
is outside the range.
The device points in the DSFR instruction
is outside the range.
The device points in the DSFL instruction
is outside the range.
The device points in the SER instruction is
outside the range.
The output decode data in the DECO
instruction exceeds the device range.
The device points in the S.AVE instruction
is outside the range.
After detecting a safety signal compare
error at the previous power-on, the
ON/OFF status of the corresponding
signal cannot be confirmed.
An error occurred in communication with
the safety signal module.
Positioning cannot be started up for the
axis during small oscillation.
Small oscillation cannot be started to the
axis to which the small oscillation has
been requested in the virtual mode
because of no clutch or clutch ON.
Clutch cannot be turned on because small
oscillation is being executed.
Small oscillation was not completed within
the specified time.
Corrective action
Correct the user safety sequence program
of the Motion CPU.
Turn off M2039 after turning on and then off
the signal where the error occurred at least
once.
Check the wiring.
Correct the program so that positioning is
not started while the small oscillation
execute flag is on.
Execute small oscillation after adding the
clutch to the corresponding axis and
confirming the clutch is OFF.
Turn the clutch command off, and turn on it
again after small oscillation is completed.
Confirm the occurrence of errors such as
servo errors or minor/major errors and
execute the small oscillation after resetting
the errors.
Correct the position of machine so that the
auxiliary sensor can move ±0.6pulse or
more at the small oscillation.
