9.4 Milling machine: Selection and cancellation of length
compensation
This function can only be selected if G00 or G01 is active. It is necessary to select the plane
perpendicular to the length compensation direction.

Only the length compensation is used from compensation memory D.. The compensation
value contained in the D word is always combined with the sign entered for the corresponding
axis.
Length compensation can be cancelled with D0. It takes effect only if the corresponding axis
has been programmed (standard machine data).
