The axis designation
for axis IV is determined
with
parameter
90. The selection
of designation
A, B or C
determines
whether
the axis is to be used for control
or display
of a rotary
axis. In this case, the axis is
relieved of mm/inch
switchover
and can operate
with
another
in linear interpolation
without
tool radius
compensation.
If U, V or W are selected,
the axis is then programmed
as an additional
linear axis, it can also be
used with
mm/inch
and can operate
with
one of the other axes in linear or circular
interpolation
with
tool
radius compensation.
