代码 402-0009: FK programming: Illegal positioning block
问题描述与安全警告
Heidenhain TNC Series CNC 触发了严重的 FK programming: Illegal positioning block 警报。需要由合格的操作员或维修技师立即处理，以防止在制造周期中对设备造成二次损坏或导致零件报废。在接触电气控制箱之前，请务必确保遵循标准安全和停机挂牌 (LOTO) 程序。
官方故障排除步骤
[Cause of error] Within an unresolved FK sequence you programmed an illegal positioning block other than FK blocks, RND/CHF, APPR/DEP, and L blocks with motion components exclusively perpendicular to the FK plane. [Error correction] First resolve the FK sequence completely or delete illegal positioning blocks. Geometry functions that are defined over the gray contouring keys and have coordinates in the working plane are illegal (exception: RND, CHF, APPR/DEP).
