- Alarm display.
Trigger a STOP D/E (settable via MD $MN_SPL_STOP_MODE) on all axes with safety
functionality, as soon as the SPL start-up phase (MD
$MN_PREVENT_SYNACT_LOCK[0,1] unequal to 0) is completed.
Analyze the value displayed and evaluate DB18: SPL_DELTA on the PLC side.
Find the difference between the monitoring channels. Possible causes:
• Incorrect wiring
• Incorrect SPL
• Incorrect assignment of the axial SGEs to internal interface $A_OUTSI
• Incorrect assignment of the axial SGAs to internal interface $A_INSI
• Incorrect assignment of the SPL SGEs to external interface $A_INSE
• Incorrect assignment of the SPL SGAs to external interface $A_OUTSE
• Different SPL startup status set in NCK and PLC
• Different SPL stop reaction set in NCK and PLC
Clear alarm with the RESET key. Restart part program
Error in data cross check NCK-PLC, stop of %1
%1 = Extension indicating the monitoring channel that triggered the stop
The monitoring channel specified in %1 (NCK or PLC) has triggered a stop D or E
(depending on the parameterization in MD $MN_SAFE_SPL_STOP_MODE). The alarm
27090 provides further information about the cause for the stop D/E.
- Alarm display.
Trigger a STOP D/E (settable via MD $MN_SPL_STOP_MODE) on all axes with safety
functionality, as soon as the SPL start-up phase (MD
$MN_PREVENT_SYNACT_LOCK[0,1] unequal to 0) is completed.
Evaluate the alarm parameters of alarm 27090 and amend the SPL, or check the I/O
modules/wiring or the internal SPL interfaces to the safety monitoring channels in the
NCK and drive 611D.
Clear alarm with the RESET key. Restart part program
Communication broken off during NCK PLC data cross check, error detected by %1
%1 = Extension indicating the monitoring channel that detected the error
The delay time (1s) for communication monitoring was exceeded in the monitoring chan-
nel specified in %1 (NCK or PLC). The other monitoring channel did not send a new data
packet within this time.
- Alarm display.
A timer of 5 secs is started, after the expiry of which
• the external NCK SPL outputs are deleted
• the PLC changes to stop.
Check the system components (the PLC must have the correct version of FB15 and
DB18).
Switch control OFF - ON.
Checksum error NCK-SPL, %1, %2, %3
%1 = Extension indicating the type of error
%2 = Extension indicating the reference variable
%3 = Extension indicating the actual variable
A checksum error has occurred in the NCK SPL. The file /_N_CST_DIR/_N_SAFE_SPF
was subsequently modified. The safe programmable logic (SPL) in the NCK may be cor-
rupted. Parameter %1 indicates the type of modification:
