Function TNC 620 iTNC 530
Behavior during presetting 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
CfgAxisPropKinn-
>presetToAlignAxis is used to
define whether the axis offset is
to be taken into account internally
after zero 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 straight
line block, then the axis offset
is added to the programmed
coordinate.
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).
Handling of preset table:

Definition of feed-rate limitation Feed-rate limitation can be defined
separately for linear and rotary
axes
Only one feed-rate limitation can
be defined for linear and rotary
axes
