代码 10950: [Channel %1: ] Calculation of arc length function too inaccurate
问题描述与安全警告
Siemens SINUMERIK 840D CNC 触发了严重的 [Channel %1: ] Calculation of arc length function too inaccurate 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
Parameters: %1 = Channel number Definitions: The calculation of the arc length function coul d not be performed to the required accuracy. Reaction: Alarm display. Warning display. Remedy: The calculation of the arc length function could not be performed to the required accuracy during active polynomial interpolation. Either in crease MD20262 $MC_SPLINE_FEED_PRECISION or reserve more memory for the representation of the arc length polynomials. MD28540 $MC_MM_ARCLENGTH_SEGMENTS defines how m any polynomial segments can be used per block in order to approximate the arc length function. Program Continuation: Clear alarm with NC ST ART or RESET key and continue the program.
