官方故障排除步驟
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.
