1 To change from incremental or absolute modes, if using lathe A, the control automatically changes the letters used
to program the axis words to the appropriate letters to generate absolute or incremental.
Each time you press the softkey corresponding to the mode, the G-code
displayed changes. When the desired mode is displayed, exit the mode
select screen by pressing the exit {
Ý } softkey.
This returns the control to softkey level 4. The next generated block has
the necessary G-codes to change the mode inserted at the beginning of the
block.
Important: This does not change the current operating mode of the
control. The control only inserts the blocks to change the operating mode
in the program. The mode does not change unless that block is executed or
unless some other MDI or program block that changes modes is executed.
6. Determine if the next move is linear or circular.
