Write access to system variable %1 only allowed from NCK-SPL
%1 = Name of safety system variable concerned
Write access to a safety system variable is only allowed from the part program /
_N_CST_DIR/_N_SAFE_SPF. If this error occurs, an instruction from another part pro-
gram was detected.
- Alarm display.
Check the part programs you are using for write accesses to safety system variables.
Clear alarm with the RESET key. Restart part program
%1 SPL protection not activated
%1 = Name of the component on which the protection is not activated (NCK or PLC)
The protection features are not activated for the SPL. The startup phase of the SPL is not
yet complete. No stop reaction (Stop D) was initiated on an error in data cross-compari-
son between NCK and PLC.
- Alarm display.
• Remedy for NCK: Activate the protection features with MD
$MN_PREVENT_SYNACT_LOCK[0,1]. The number range of the synchronized action
IDs used in the SPL must be entered in this MD.
• Remedy for PLC: Activate the protection features by setting the appropriate data bit in
DB18.
Clear alarm with the RESET key. Restart part program
SPL start not allowed
To start the SPL in protected state (MD $MN_PREVENT_SYNACT_LOCK[0,1] not equal
0) Safety Integrated functionality must first be activated for at least one axis (via MD
$MA_SAFE_FUNCTION_ENABLE). Without this functionality it is only possible to oper-
ate SPL in start-up state.
- Mode group not ready.
- Channel not ready.
- Channel not ready.
- NC Start disable in this channel.
- NC Stop on alarm.
- Alarm display.
- Interface signals are set.
Start up axial Safety Integrated functionality or remove the SPL protection via MD
$MN_PREVENT_SYNACT_LOCK[0,1].
Switch control OFF - ON.
At least one axis is not safely referenced
There are two reasons for this alarm:
• the machine position of at least one of the axes monitored with SI has not yet been
acknowledged by the user, or
• the machine position of at least one of the axes monitored with SI has not yet been ver-
ified through follow-up referencing.
Even if the axis is already referenced, there is no confirmation that referencing has sup-
plied the correct result. For example, wrong results can occur if the axis was moved after
the control was switched off, with the result that the standstill position saved prior to
switching off is no longer correct. To make sure that this does not happen, the user must
acknowledge the displayed actual position after the first referencing process.
