- Interface signals are set.
- Alarm display.
Remedy: Program only one type, in other words when transformation is switched on program either
Euler angles only or orientation vectors (direction vectors) only.
Program Con- Clear alarm with NC START or RESET key and continue the program.
tinuation:
14111
Channel %1 block %2 Euler angles, orientation vector and transformation axes pro-
grammed
Parameters: %1 = Channel number
%2 = Block number, label
Definitions: An orientation has been programmed at the same time as Euler angles or components of
an orientation vector and the machine axis influenced by the orientation.
Example:
N50 TRAORI (1)
N55 A2=70 B2=10 C2=0 X50 ; alarm, because Euler angle and axes were programmed
Reactions: - Correction block is reorganized.
- Interface signals are set.
- Alarm display.
Remedy: Program only one type, in other words with transformation switched on program either
Euler angles only or orientation vectors (direction vectors) only or deselect transformation
(TRAFOOF) and set tool orientation by programming the auxiliary axes.
Program Con- Clear alarm with NC START or RESET key and continue the program.
tinuation:
14112
Channel %1 block %2 programmed orientation path not possible
Parameters: %1 = Channel number
%2 = Block number, label
Definitions: In 5-axis transformation, the two orientation axes place a coordinate system comprising
lengths and circles of latitude on a spherical surface.
If the interpolation traverses the pole point, only the 5th axis will move and the 4th axis will
retain its starting position. If a motion is programmed that does not traverse the pole point
directly, but passes it very closely, the preset interpolation will be deviated from if the path
forms a circle that is defined by the machine data: 24530 TRAFO5_NON_POLE_LIMIT_1
(changeover angle that refers to the 5th axis). The interpolated contour is then placed
through the pole (in the immediate vicinity of the pole, the 4th axis would otherwise have
to accelerate most rapidly and then decelerate again).
For the 4th axis, the result is a position deviation as compared to the programmed value.
The maximum permissible angle which the programmed and the interpolated path may
include is stored in the MD 24540 TRAFO5_POLE_LIMIT.
Reactions: - Correction block is reorganized.
- Interface signals are set.
- Alarm display.
Remedy: In the vicinity of the pole, always make use of axis programming. Programming of tool ori-
entations close to the pole should generally be avoided because this always leads to
problems concerning dynamic response.
Program Con- Clear alarm with NC START or RESET key and continue the program.
tinuation:
14113
Channel %1 block %2 programmed lead angle too large
Parameters: %1 = Channel number
