- 146 -
NOTE
1 This code is disabled when bit 4 (NVGA) of compile
parameter (No. 9167) is set to 1.
2 The commands of addresses X, Y, I, and J are:
- Absolute commands at all times when bit 3
(INCD) of compile parameter (No. 9167) is set to
0.
- When bit 3 (INCD) of compile parameter (No.
9167) is set to 1, the commands of addresses X
and Y are switched between absolute and
incremental commands by G390/G391.
- The command values of addresses I and J are
based on the vector from the start point of an arc
to the center of the arc.
