Channel %1 axis %2 no handwheel assigned for overlaid motion
%1 = Channel number
%2 = Axis number
No handwheel has been assigned for this specified axis after handwheel overlay has
been started in automatic mode. If the axis identifier is missing in the alarm with active
velocity overlay FD > 0, then the 1st geometry axis has not been defined in the NC chan-
nel. In this case the block is executed without handwheel control.
- Alarm display.
If handwheel control is required, a handwheel must be activated.
Alarm display showing cause of alarm disappears. No further operator action necessary.
Channel %1 axis %2 braking position cannot be accepted as a new reversing posi-
tion
%1 = Channel number
%2 = Axis number
On changing the reciprocation reversal from external sources, the braking position cannot
be accepted as a new reversing position, since changing the reversal point via handwheel
or JOG key is active.
- Alarm display.
Deselect VDI signal "Change reversal point" and reselect it either
• with "Reciprocation reversal from external sources" or
• by changing the reversal point by means of handwheel or
• by changing the reversal point via JOG key.
Alarm display showing cause of alarm disappears. No further operator action necessary.
Channel %1 contour handwheel: traverse direction or overtravel of beginning of
block not allowed
%1 = Channel number
Travel takes place on the path with the contour handwheel in the opposite direction to the
programmed travel direction and the starting point of the path has been reached at the
start of the block.
- Alarm display.
Turn the contour handwheel in the opposite direction.
Alarm display showing cause of alarm disappears. No further operator action necessary.
Axis %1 travel to fixed stop not possible. Check programming and axis data.
%1 = Axis name, spindle number
1. The "Traverse against fixed stop" function has been programmed with FXS[AX]=1 but
the axis does not (yet) support this. Check MD 37000. This function is not available for
gantry axes and simulated axes.
2. On selection, no movement was programmed for axis AX. AX is a machine axis identi-
fier.
3. It is always necessary to program a traversing movement in the selection block for the
axis/spindle for which the "Traverse against fixed stop" function is activated.
The alarm can be reprogrammed in the MD ALARM_REACTION_CHAN_NOREADY
(channel not ready).
