# Sinumerik Alarm 14094 Channel %1 block %2 polynominal degree greater than 3 programmed for polynominal interpolation

Sinumerik Alarm 14094 Channel %1 block %2 polynominal degree greater than 3 programmed for polynominal interpolation

Parameters:
%1 = Channel number
%2 = Block number, label

Definitions:
The polynomial degree in the polynomial interpolation is based on the number of programmed coefficients for an axis. The maximum possible polynomial degree is 3, i.e. the axes are according to the function: f(p) = a0 + a1 p + a2 p2 + a3 p3 The coefficient a0 is the actual position at the start of interpolation and is not programmed!

Reactions:
– Alarm display.
– Interface signals are set.
– Correction block is reorganized.

Remedy:
Reduce the number of coefficients. The polynomial block may have a form no greater than the following:
N1 POLY PO[X]=(1.11, 2.22, 3.33) PO[Y]=(1.11, 2.22, 3.33)
N1 PO[n]=… PL=44
n … n … axis identifier, max. 8 path axes per block

Program Continuation:
Clear alarm with NC START or RESET key and continue the program.
