SINUMERIK 840D sl/SINAMICS S120 SINUMERIK Safety Integrated (FBSI sl) – 05.2008 Edition
10.2 NCK safety alarms for SINUMERIK 840D sl
Write access to system variable %1 only allowed from NCK–SPL
%1 = name of the safety system variable involved
It is only possible to write access one of the safety system variables
from the part program /_N_CST_DIR/_N_SAFE_SPF. If this error oc-
curs, an instruction from another part program was detected.
Alarm display
Check the part program used to write access safety system variables.
Clear the alarm with the RESET key. Restart the part program.
%1 SPL protection not activated
%1 = name of the component for which the protection is not activated
(NCK or PLC)
The protective mechanisms for the SPL have not been activated. The
commissioning phase of the SPL has not yet been completed. For an
error in the crosswise data comparison between NCK and PLC, a stop
response (Stop D or E) is not initiated.
Alarm display
Remedy for NCK: Activate the protective mechanisms by writing to MD
$MN_PREVENT_SYNACT_LOCK [0,1]. The number range of the
synchronous action IDs used in the SPL must be entered in this MD.
Remedy for the PLC: Activate the protective mechanisms by setting the
appropriate data bit in DB18.
Clear the alarm with the RESET key. Restart the part program.
SPL start not allowed
To start the SPL in the protected state ($MN_PREVENT_SYN-
ACT_LOCK[0,1] not equal to 0), at least one axis must have Safety
Integrated functionality activated (via MD $MA_SAFE_FUNC-
TION_ENABLE) beforehand. Without this functionality it is only pos-
sible to operate the SPL in the commissioning state.
Mode group not ready
Channel not ready
NC start inhibit in this channel
NC stop for alarm
Alarm display
Interface signals are set
Commissioning the axial Safety Integrated functionality or cancellation
of the SPL protection using MD $MN_PREVENT_SYNACT_LOCK[0,1]
