17813 [Channel %1: ] Axis %2 fixed-point approach in JOG and override motion
active
Parameters: %1 = Channel number
%2 = Axis name, spindle number
Definitions: 'Fixed-point approach in JOG' is active for the axis, but another offset motion - for example a synchro-
nization offset $AA_OFF - has been interpolated simultaneously.
The position of the selected fixed-point is not reached if offset values are changed during the travers-
ing motion.
The target point then becomes "fixed-point position + change in offset value".
The end point 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:
17814 [Channel %1: ] Axis %2 fixed-point position not available
Parameters: %1 = Channel number
%2 = Axis name, spindle number
%3 = Number of fixed-point position
Definitions: No fixed-point position is available for the fixed point selected in JOG mode. See MD30610
$MA_NUM_FIX_POINT_POS.
Reaction: Correction block is reorganized.
Interface signals are set.
Alarm display.
Remedy: Adapt MD30610 $MA_NUM_FIX_POINT_POS and, if necessary, MD30600
$MA_FIX_POINT_POS[].
Deselect fixed-point approach or select a valid fixed point, and restart the JOG motion.
Program Con- Clear alarm with the Delete key or NC START.
tinuation:
17815 Indexing axis %1 fixed point %2 unequal indexing position
Parameters: %1 = Axis number
%2 = Array index of machine data
Definitions: The axis is a referenced indexing axis, and the fixed-point number %2 to be approached in JOG mode
(defined in MD30600 $MA_FIX_POINT_POS) 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: MD30600 $MA_FIX_POINT_POS[] or adapt the indexing positions.
Program Con- Clear alarm with the RESET key. Restart part program
tinuation:
17820 [Channel %1: ] JOG to position not possible for axis %2, reason %3
Parameters: %1 = Channel number
%2 = Axis name, spindle number
%3 = Cause
Definitions: A 'JOG to position' has been requested for an axis. This is not possible because:
Reason 1: The axis is involved in the active transformation.
Reason 2: The axis is a following axis in an active coupling.
The JOG to position will therefore not be executed.
Reaction: Interface signals are set.
Alarm display.
