Basic Theory
Brief description of typical, frequently used ISO codes
After pressing “OK”, the system
restarts automatically.
After restarting, press “Shift” +
“System - Alarm” again and if the
symbol in the red circle appears,
ISO mode is already activated.
A red ISO appears at the top of the screen and the ISO mode button on the right is
highlighted in blue.
Method 2
When using method 2 to activate the ISO mode, it will exit
ISO mode and return to the default DIN mode via “Reset”
button or after finishing the machining program.
Insert G291 in the first line of the ISO part program to be executed and insert G290 in
front of M30.
G291/G290
commands must
be set separately
in a line!
If ISO is displayed at the top of the screen, it is activated.
