YASNAC PCNC Programming Manual Chapter 4: Enhanced Level Commands
(c) Example of control instructions using modal information
With the programs indicated above, the Z-axis returns to the initial point level. When giv-
ing the commands for initial point level return (G98) and R-point level return (G99), it is
possible to change the command that specifies the tool return level according to the
present mode (G98 or G99); the present mode is found by checking the modal informa-
tion. For this check, modal information variable can be used.
• System variable #4010 should be used since G98 and G99 are G code of 10-group.
• To change the tool return level command, use “IF • • • GOTO • • • command.
• It is possible to retain the G code of 0-group, which is valid before the execution of a
macroprogram, after the execution of the macroprogram. “G codes of 01-group”
means G00, G01, G02, G03.
