Sinumerik Alarm 10950 Channel %1 calculation of arc length function too inaccurate
Parameters:
%1 = Channel number
Definitions:
The calculation of the arc length function could not be performed to the required accuracy.
Reactions:
– 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 increase MD SPLINE_FEED_PRECISION or reserve more memory for the representation of the arc length polynomials. MD MM_ARCLENGTH_SEGMENTS defines how many polynomial segments can be used per block in order to approximate the arc length function.
Program Continuation:
Clear alarm with NC START or RESET key and continue the program.
