Interpolation with Following Error 'G07'
A following-error-containing algorithm is activated for the axis moves us-
ing the interpolation condition G07. G07 is the power-on state. It is active
and latched until it is overwritten by a G06. G07 is reset automatically at
the end of the program (RET) or by the BST, M02, M30 command. NC-
block transitions which are not tangential will be rounded.

Fig. 4-6: Circular interpolation with F8000 mm/min and G07
In the circle shown here (Fig. 4-6) the actual contour is multiplied by an ex-
pansion factor of 527.5. By contrast, the expansion factor with G06 was a
multiplier of 1693.7—more than three times the value—which explains the
variation in the position deviation. Here is the part program for the circle
plots (Figs. 4-6 to 4-9).
