Programmed
When the control generates 3 motion blocks, the length of the second
generated block is checked against a minimum allowable length,
determined in AMP by your system installer. The amount of motion of the
second move on the two axes in the compensation plane is compared to the
minimum allowed value for each axis. If both are less than the allowed
value, then the control does not execute the second generated block. The
path of the third generated block is then altered to position the cutting tool
along a linear path to the original end-point of the third generated block.
See Figure 21.38 for a pictorial representation.
