Axis Motion
Chapter 12
12-12
The control offers a variety of sample patterns with prompting to aid in the
programming of QuickPath Plus. These are found under the QuickView
feature described in chapter 5.
Remember these points when programming QuickPath Plus:
Your system installer may have assigned ,A (rather than A) as the angle
word.
Any axis words that are programmed must be in the current plane, and
angles are measured from the first axis defining that plane. All
examples in this section assume the ZX plane is active (angles are
measured relative to the Z axis)
The angle word (A) is always interpreted as an absolute angle regardless
of the current mode (G90 or G91)
The L--word is always interpreted as an incremental distance from the
current position regardless of the current mode (G90 or G91). Radius or
diameter mode (G07 - G08) has no effect on the A-- or L--word
If you must program more than one block to perform the QuickPath Plus
operation being used and an error is made in one of the program blocks,
the control always shows the error as being in the first block regardless of
which block it is really in. If programming in <SINGLE BLOCK> mode,
the control stops after the execution of the first block as normal
If you must program more than one block to perform the QuickPath
Plus operation being used, a maximum of 4 non-motion blocks can be
programmed between those blocks. A non-motion block is any block
that does not generate axis motion in the current plane
These G--codes cause a syntax error if programmed in any QuickPath
Plus block:
All G--codes in G--code Group 0 (except G04, G09, and G60)
All G--codes in G--code Group 1 (except G00, G01, G02, and G03)
All G--codes in G--code group 4, 6, 9, 10, 11, and 16
For a listing of G--codes and their group numbers, refer to the G-code
table in appendix C of this manual.
If you must program more than one block to perform a QuickPath Plus
operation, it causes an error if the current plane is changed to some
other parallel plane in between those blocks
If you program an angle in a circular QuickPath Plus block, an error
occurs
