04.00 Edition
An alarm is output if a denominator polynomial with
zeros is programmed within the interval [0,PL] when
polynomial interpolation is active. Denominator
polynomials have no effect on the motion of special
axes.
Additional notes
Tool radius compensation can be activated with
G41, G42 in conjunction with polynomial
interpolation and can be applied in the same way as
in linear or circular interpolation modes.
