TNC 640
The jog increment can be defined
separately for linear and rotary
axes
Basic transformation (translation
and rotation) of machine table
system to workpiece system via
the X, Y and Z columns, as well as
spatial angles SPA, SPB and SPC.
In addition, the X_OFFS to W_OF-
FS columns can be used to define
the axis offset of each individ-
ual axis. The function of the axis
offsets can be configured.
Line 0 can also be edited manually.
Presetting in a rotary axis has the
same effect as an axis offset. This
offset is also effective for kinemat-
ics calculations and during tilting of
the working plane.
In machine parameter preset-
ToAlignAxis (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
Only after a reference run is it
possible to set a preset or to
modify a preset via the preset
table.

Feed-rate limitation can be defined
separately for linear and rotary
axes
iTNC 530
The jog increment applies for both
linear and rotary axes
Basic transformation (transla-
tion) of machine table system to
workpiece system via the columns
X, Y and Z, as well as a ROT basic
rotation in the working plane
(rotation).
In addition, columns A to W can
be used to define presets on the
rotary and parallel axes.
Line 0 can only be edited by
manual probing cycles.
Rotary axis offsets defined by
machine parameters do not influ-
ence the axis positions that were
defined in the Tilt working plane
function.
MP7500, bit 3 permits you to
define whether the current
rotary axis position relative to
the machine datum is taken into
account or whether the first rotary
axis (usually the C axis) is assumed
to be in 0° position.
A preset can be set or modified via
the preset table before a reference
run.
Available
Only one feed-rate limitation can
be defined for linear and rotary
axes
