Restrictions
After an external or internal stop, you can only re-enter the
contour with the function
RESTORE POS. AT N
. Before you start
the block scan, you must cancel
M120
, otherwise the control
will generate an error message.
If you want to approach the contour on a tangential path, you
must use the
APPR LCT
function. The block with
APPR LCT
must contain only the coordinates of the working plane.
If you want to depart the contour on a tangential path, you
must use the function
DEP LCT
. The block with
DEP LCT
must
contain only the coordinates of the working plane.
Before using the functions listed below, you have to cancel
M120
