Overview of Alarms
- Alarm display.
- NC Stop on alarm at block end.
Remedy: Modify part program.
Program Con- Clear alarm with NC START or RESET key and continue the program.

Channel %1 block %2 end point specification during angle programming contradic-
tory
Parameters: %1 = Channel number
%2 = Block number, label
Definitions: During programming of a straight line, both positions of the active plane and an angle
were specified (the position of the end point is over-specified), or the position of the pro-
grammed coordinate cannot be reached with the specified angle. If a contour consisting
of two straight lines is to be programmed with angles, it is possible to specify the two axis
positions of the plane and an angle in the second block. The error can also occur if, due to
a programming error, the preceding block cannot be interpreted as the first subblock of
such a contour. A block is interpreted as the first block of a two-block contour if an angle,
but not an axis of the active plane, was programmed, and if the block is not already the
second block of a contour.
Reactions: - Correction block is reorganized.
- Local alarm reaction.
- Interface signals are set.
- Alarm display.
- NC Stop on alarm at block end.
Remedy: Modify part program.
Program Con- Clear alarm with NC START or RESET key and continue the program.

Channel %1 block %3 axis %2 is not a geometry axis
Parameters: %1 = Channel number
%2 = Axis name, spindle number
%3 = Block number, label
Definitions: With an active transformation or a frame with a rotation component the geometry axes are
needed for block preparation. If a geometry axis has previously been traversed as posi-
tioning axis, it retains its status of "positioning axis" until it is again programmed as a
geometry axis.
Because of the POSA motion beyond block boundaries, it is not possible to identify in the
preprocessing run whether the axis has already reached its target position when the block
is executed. This is, however, an unconditional requirement for calculating the ROT com-
ponent of the frame or of the transformation.
If geometry axes are used as positioning axes, then:
1. No rotation may be specified in the current overall frame.
2. No transformation may be selected.
Reactions: - Correction block is reorganized.
- Local alarm reaction.
- Interface signals are set.
- Alarm display.
Remedy: After selecting transformation or frame, reprogram the geometry axis now operating as
positioning axis (e.g. with WAITP) in order to revert the status to "geometry axis.
Program Con- Clear alarm with NC START or RESET key and continue the program.
