AxisMotion

The format for these blocks is as follows:
N1 A__;
N2 A__Z__X__;
Where: Is :
A Angle
this word, determined in AMP by your system installer, defines the
angle ofa linear path. T his manual assumesthatthe A--wordis used.
The angle is a positive value when measuredcounter-clockwise from
thefirstaxis definingthe currentlyactive plane and a negativevalue
when measuredclockwise. The angle is in unitsofdegrees.
ZX End Point of
second block
a representation oftheactual coordinatesofthe end pointof the
secondblock. They mustbe programmed asabsolute valuesand
mustbe axesinthecurrentplane.
Important: There can be as many as 4 program blocks between the two
QPP blocks; however, those blocks cannot generate axis motion in the
current plane.
Both of these blocks must be programmed in the same plane. If the current
plane is changed between blocks, the control generates an error.

If the control cannot determine an intersection point for the two linear
paths (for example, if the paths are parallel), an error occurs.
