When presetting, the positions of the tilting axes must
match the tilted situation.
The behavior of the control during presetting depends
on the setting in the optional machine parameter
chkTiltingAxes
(no. 204601).
Further information: "Introduction", Page 204
PLANE RESET
does not reset the active 3-D ROT.
In row 0 the control always saves the preset that you
most recently set manually via the axis keys or via soft
key. If the preset set manually is active, the control
displays the text
PR MAN(0)
in the status display.
Copying the preset table
Copying the preset table into another directory (for data backup)
is permitted. Write-protected lines are also write-protected in the
copied tables.
Do not change the number of lines in the copied tables! If you want
to reactivate the table, this may lead to problems.
To activate the preset table copied to another directory you have to
copy it back.
If you select a new preset table, you need to reactivate the preset.
