TNC 620
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 rates can be defined
separately for linear and rotary
axes
Press the F soft key in the Manual
operation mode to define a
separate feed rate for linear and
rotary axes. These feed rates apply
only in the Manual operation
mode.

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.
Only one feed-rate can be defined
for linear and rotary axes
