Information area
The form for the
Global Program Settings
function has an
information area located in its upper left half. It contains the
following:
Active unit of meas.
: Unit of measurement for entering values
Further information: "Setting the unit of measure ",
page 856
Active preset number
: Preset management row
Further information: "Activating a preset", page 746
3-D basic rotation
: Spatial angle from preset management
Further information: "General status display", page 98 and
page 765
Additive offset (M-CS)
Refer to your machine manual.
Your machine tool builder can also disable individual
settings possibilities within the
Global Program Settings
function.
Axes that are not included in the kinematics description
are always grayed out and therefore not editable!
The
Additive offset (M-CS)
option of the
Global Program Settings
function provides a coordinate transformation in the M-CS machine
coordinate system.
Further information: "Machine coordinate system M-CS",
page 148
The additive offset of the
Global Program Settings
takes effect on
an axis-by-axis basis. This value is added to the corresponding axis-
specific offset from
Preset management
.
Further information: "Saving presets in the table", page 739
Refer to your machine manual.
In machine parameter
presetToAlignAxis
(no. 300203)
your machine tool builder specifies for each axis what
effect an offset of a rotational axis has on the preset.
True
(default): The offset is subtracted from the axis
value before the calculation of the kinematics
False
: The offset only affects the position display
NOTICE
Danger of collision!
The setting of the
presetToAlignAxis
(no. 300203) machine
parameter determines if a preset is shifted along with an
rotary axis offset or not. There is a danger of collision during
subsequent machining!
Test the behavior at the machine
If necessary, reset the preset after the offsets have been
activated (mandatory for table rotary axes)
