1324* Tolerance for safe standstill exceeded
Scan
After selection of safe standstill
After initiation of STOP C, D, E and expired timer
Effect
Display of the alarm
Initiation of STOP B and A
Explanation
The axis has moved too far from the set position, i.e. further than permitted in MD 4180*: (standstill tolerance for
safe operation).
Remedy
Check the tolerance of the standstill monitoring:
If the value does not match the accuracy and dynamic control response of the axis –> increase the tolerance.
If the value matches the accuracy and dynamic control response of the axis –> inspect the machine for damage
and repair the damage.
Note
Applies as from SW 5.4.
1328* Safe speed exceeded
Scan
After selection of safe speed
Effect
Display of the alarm
Initiation of STOP C, D, E (depending on configuration)
Explanation
The axis has moved too quickly, i.e. faster than permitted in MD 4184*, 4188*, 4192*, 4196*: (limit value for safe
speed 1, 2, 3, 4).
Remedy
If no apparent operating error occurred:
Check the input value of the MD, check the SGEs: of the 4 available speeds, was the correct one selected? If
MDs and SGEs are correct, inspect the machine for damage and repair the damage.
Note
Applies as from SW 5.4.
1332* Safe end position exceeded
Scan
After enabling of the safe end position function
Effect
Display of the alarm
Initiation of STOP C, D, E (depending on configuration)
Explanation
The axis has traveled beyond the end position entered in MD 4200*, 4204*: (upper limit for safe end position 1, 2)
or MD 4208*, 4212*: (lower limit for safe end position 1, 2).
Remedy
If no apparent operating error occurred:
Check the input value of the MD, check the SGEs: of the 2 end positions, was the correct one selected? If MDs
and SGEs are correct, inspect the machine for damage and repair the damage.
Continuation
Cancel the user enable for this axis. Then activate the RESET key. The program is aborted and the alarm is
cleared. Move the axis into the valid travel range in JOG mode. When the error in the NC program has been reme-
died and the position of the axis has been checked, the user enable can be reactivated and the program started.
Note
Applies as from SW 5.4.
1336* Failure in a monitoring channel
Scan
After selection of at least one safety function
Effect
Display of the alarm
NC START interlock
STOP F
STOP B and A on active SI function
Explanation
The comparison of both monitoring channels has uncovered a difference between the input data or the monitoring
results. One of the monitoring functions is no longer operating reliably, i.e. safe monitored operation is no longer
possible.
Remedy
Find the difference between the monitoring channels. The error code that indicates the cause appears in the fol-
lowing machine data:
on 840C
on 611D
The meaning of the error code can be found in the error code table for STOP F on the 840C. It is possible that the
safety–related machine data are no longer identical (load them again if necessary) or that the SGEs do not have
the same signal level (measure again or check in the SI service display). If no such error is found, an error may
have occurred in the CPU, such as a corrupt memory cell. This error can be transient (remedied by POWER ON)
or permanent (reoccurs after POWER ON, in this case replace the hardware).
Continuation
Remedy the error, and press the RESET key. The program is aborted. If safe monitoring was active, STOP B was
also initiated automatically. In this case, it is necessary to switch the control off and on (POWER ON).
Note
Applies as from SW 5.4.
