Sinumerik Alarm 10891 Channel %1 block %2 multiplicity of node is greater than its order
%1 = Channel number
%2 = Block number, label
In the B spline the distance between nodes PL (node = point on spline at which 2 polynomials meet) has been programmed with zero too often in succession (i.e. the “multiplicity” of a node is too great). In the quadratic B spline the node distance may not be specified more than twice with zero in succession, and in the cubic B spline not more than three times.
– Local alarm reaction.
– Alarm display.
– Interface signals are set.
– Correction block is reorganized.
Program the node distance PL = 0 in succession no more than the degree of the B spline used.
Clear alarm with NC START or RESET key and continue the program.
