Definitions: The programmed orientation vectors (direction vectors) in the beginning of block and end of block
point include an angle of 180 degrees. Therefore the interpolation plane cannot be determined.
Example:
N50 TRAORI (1)
N55 A3=0 B3=0 C3=1
N60 A3=0 B3=0 C3=-1 ; the vector of this block is precisely opposite to that in the preceding block.
Reaction: Correction block is reorganized.
Interface signals are set.
Alarm display.
Remedy: Modify the part program so that the orientation vectors of a block are not directly opposed to each
other, for instance by dividing the block up into 2 subblocks.
Program Con- Clear alarm with NC START or RESET key and continue the program.
tinuation:
14121 [Channel %1: ] Block %2 no orientation defined (distance equals zero).
Parameters: %1 = Channel number
%2 = Block number, label
Definitions: The programmed coordinates for the 2nd space curve with XH, YH, ZH
do not define any tool orientation, as the distance of the curve to the TCP is becoming zero.
Reaction: Correction block is reorganized.
Interface signals are set.
Alarm display.
Remedy: Change the part program so that the distance between the two curves is not becoming zero and
that a tool orientation is defined.
Program Con- Clear alarm with NC START or RESET key and continue the program.
tinuation:
14122 [Channel %1: ] Block %2 angle and direction of the cone programmed
Parameters: %1 = Channel number
%2 = Block number, label
Definitions: With taper circumference interpolation of orientation with ORICONCW and ORICC, only the opening
angle or the direction of the taper may be programmed. Programming of both in one single block is
not allowed.
Reaction: Correction block is reorganized.
Interface signals are set.
Alarm display.
Remedy: Modify part program.
Program Con- Clear alarm with NC START or RESET key and continue the program.
tinuation:
14123 [Channel %1: ] Block %2 nutation angle of the cone too small
Parameters: %1 = Channel number
%2 = Block number, label
Definitions: With taper circumference interpolation, the programmed opening angle of the taper must be greater
than the half of the angle between the start and end orientation. Otherwise, a taper cannot be defined.
Reaction: Correction block is reorganized.
Interface signals are set.
Alarm display.
Remedy: Modify part program.
Program Con- Clear alarm with NC START or RESET key and continue the program.
tinuation:
14124 [Channel %1: ] Block %2 start tangent for orientation is zero
Parameters: %1 = Channel number
%2 = Block number, label
Definitions: With taper circumference interpolation with tangential continuation (ORICONTO), the start tangent of
orientation must not be zero.
Reaction: Correction block is reorganized.
Interface signals are set.
Alarm display.
