Basic Theory
All the ISO codes described in this unit
can be implemented in the ISO mode of
the 808D system!
After pressing
“OK”, the sys-
tem restarts auto-
matically.
After restarting,
press “Shift” +
“System - Alarm”
again and if the
symbol in the red
circle appears,
ISO mode is al-
ready 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.
G291/G290 com-
mands must be set
separately in a line!
Insert G291 in the first line of the ISO part program to be executed and
insert G290 in front of M30.
If ISO is displayed at the top of the screen, it is
activated.
