Overview of Alarms
NCK alarms
Remedy: Deselect 'JOG to position', or previously deselect the transformation with TRAFOOF or disband the
coupling.
Program Con- Clear alarm with the Delete key or NC START.
tinuation:
17821 [Channel %1: ] Axis %2 JOG to position and override motion active
Parameters: %1 = Channel number
%2 = Axis name, spindle number
Definitions: 'JOG to position' is active for the axis, but an offset motion - for example a synchronization offset
$AA_OFF - has been interpolated simultaneously.
The position of the SD43320 $SA_JOG_POSITION is not reached if offset values are changed during
the traversing motion.
The target point then becomes "Jog position + change in offset value".
The position SD43320 $SA_JOG_POSITION will be reached if the traversing motion is restarted after
the offset value has been changed.
(For example: incremental traversing in which the traversing motion stops intermittently).
Reason:
Restarting the motion takes the current offset value into account.
Reaction: Interface signals are set.
Alarm display.
Remedy: Trigger JOG motion again.
Program Con- Clear alarm with the Delete key or NC START.
tinuation:
17822 [Channel %1: ] Axis %2 JOG to position: Position changed
Parameters: %1 = Channel number
Definitions: An axis motion is active for the axis with 'JOG to position' but the position, that is the content of
SD43320 $SA_JOG_POSITION, has been changed. The approach motion is canceled.
Reaction: Interface signals are set.
Alarm display.
Remedy: Trigger JOG motion again.
Program Con- Clear alarm with the Delete key or NC START.
tinuation:
17823 [Channel %1: ] Axis %2 JOG to position deactivated
Parameters: %1 = Channel number
Definitions: An axis motion is active for the axis with 'JOG to position' but 'JOG to position' has been deactivated.
The approach motion is canceled.
Reaction: Interface signals are set.
Alarm display.
Remedy: Trigger JOG motion again.
Program Con- Clear alarm with the Delete key or NC START.
tinuation:
17825 Indexing axis %1 $SA_JOG_POSITION unequal indexing position
Parameters: %1 = Axis number
Definitions: The axis is a referenced indexing axis and 'JOG to position' is activated in JOG mode, but SD43320
$SA_JOG_POSITION does not coincide with an indexing position. In JOG mode, referenced indexing
axes approach indexing positions.
Reaction: NC not ready.
NC Start disable in this channel.
Interface signals are set.
Alarm display.
NC Stop on alarm.
Remedy: Modify SD43320 $SA_JOG_POSITION or indexing positions.
Program Con- Clear alarm with the RESET key. Restart part program
tinuation:
