Code 14112: [Channel %1: ] Block %2 programmed orientation path not possible
Issue Description & Safety Warning
The Siemens SINUMERIK 840D CNC has triggered a critical [Channel %1: ] Block %2 programmed orientation path not possible alarm. Immediate attention from a qualified operator or maintenance technician is required to prevent secondary damage to the equipment or spoiled parts during the manufacturing cycle. Always ensure standard safety and LOTO procedures are followed before accessing electrical cabinets.
Official Troubleshooting Steps
Parameters: %1 = Channel number %2 = Block number, label Definitions: In 5-axis transformation, the two orientation ax es place a coordinate system comprising lengths and circles of latitude on a spherical surface. If the interpolation traverses the pole point, only the 5t h axis will move and the 4t h 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 devia ted from if the path forms a circle that is defined by the machine data: MD24530 $MC_TRAFO5_NON_POLE_LIMIT_1 (changeover angle that refers to the 5th axis). The interpolated contour is then plac ed through the pole (in the immediate vicinity of the pole, the 4th axis would otherwise have to a ccelerate most rapidly and then decelerate again). For the 4th axis, the result is a position deviati on as compared to the programmed value. The maximum permissible angle which the programmed and the interpolated path may include is stored in the MD24540 $MC_TRAFO5_POLE_LIMIT. Reaction: 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 orientations close to the pole should generally be avoided bec ause this always leads to problems concerning dynamic response. Program Continuation: Clear alarm with NC ST ART or RESET key and continue the program.
