TNC 620
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 L block, then
the axis offset is added to the
programmed coordinate.
Possible
Not available
Feed-rate limitation can be
defined separately for linear and
rotary axes
iTNC 530
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).
Not possible
Available
Only one feed-rate limitation can
be defined for linear and rotary
axes
