Program Continuation:

Channel %1 block %2 programmed orientation path not possible

%1 = Channel number %2 = Block number, label

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.

-    Correction block is reorganized.

-    Interface signals are set.

-    Alarm display.

In the vicinity of the pole, always make use of axis programming. Programming of tool orientations close to the pole should generally be avoided because this always leads to problems concerning dynamic response.

Clear alarm with NC START or RESET key and continue the program.
