Remedy for NCK: Activate the protective mechanisms by writing to
MD11500 $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 permitted
To start the SPL in the protected state (MD11500 $MN_PRE-
VENT_SYNACT_LOCK[0,1] not equal to 0), at least one axis must
have Safety Integrated functionality activated (via MD36901
$MA_SAFE_FUNCTION_ENABLE) beforehand, and operated with
active drive.
In addition, at least one SGE/SGA of this axis must have been para-
meterized at an SPL interface. Without this functionality it is only
possible to operate the SPL in the commissioning state.
