If you program an L--word in a G13, or G13.1 block, an error occurs
This section describes 3 programming situations in which QuickPath Plus
can be used:
Only one end coordinate known
No end coordinate known (L)
No intersection known
One End Coordinate Known
Many times part drawings give a programmer only one axis endpoint for a
path and require that the other axis endpoint be calculated by using a given
angle. The following QuickPath Plus feature eliminates the need for this
calculation. This must be a linear block. See page 12-17 for circular
QuickPath Plus.
The format for this block is as follows:
A__ X__ ;
Z__
Where : Is :
A Angle this word, determined in AMP by your system installer, defines the angle
of a linear path. This manual assumes that the A--word is used. The
angle is a positive value when measured counterclockwise from the first
axis defining the currently active plane and a negative value when
measured clockwise. The angle is in units of degrees.
X,Z End Point this word is used to program one of the coordinates of the end point of a
linear path. The control calculates the other end point automatically. This
can be any axis word that is in the current plane.
You can only program one axis word from the active plane in this block.
Any axis word that is not in the current plane is executed as a normal linear
move to that coordinate and combined with the QuickPath Plus generated
path. If both axis words from the current plane are entered in the block,
the angle is ignored and the control moves to the coordinate position
programmed with the axis words. All examples in this section assume the
ZX plane is active.
Important: If the value of the angle (A--word) is 0
°
or 180
°
, the second
axis in the active plane must be programmed in the block as the endpoint.
If the value of the angle is 90
°
or 270
°
, the first axis in the active plane
must be programmed in the block as the endpoint.
