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_OFFS columns can be used
to define the axis offset of each
individual axis. The function of the
axis offsets can be configured.
Presetting in a rotary axis has
the same effect as an axis offset.
The offset is also effective for
kinematics calculations and for
tilting the working plane.
The machine parameter
presetToAlignAxis (no. 300203)
is used to define whether the axis
offset is to be taken into account
internally after datum setting.
Independently of this, an axis
offset has always the following
effects:
An axis offset always
influences the nominal position
display of the affected axis (the
axis offset is subtracted from
the current axis value).
If a rotary axis coordinate is
programmed in an L block, then
the axis offset is added to the
programmed coordinate.
Not available
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 (translation)
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 datums on the
rotary and parallel axes.
Rotary axis offsets defined by
machine parameters do not
influence the axis positions that
were defined in the Tilt working
plane function.
MP7500 bit 3 defines whether
the current rotary axis position
referenced to the machine datum
is taken into account, or whether
a position of 0° is assumed for the
first rotary axis (usually the C axis).
Available
Only one feed-rate limitation can
be defined for linear and rotary
axes
