1.2.4 Specifying the Rotation Axis
Overview
Parameter ROTx (No.1006#0) can be used to set each axis to a linear
axis or rotation axis. Parameter ROSx (No. 1006#1) can be used to
select the rotation axis type, A or B, for each axis. See the explanation
of the parameters for details of types A and B.
When the roll over function is used, the values displayed for absolute
coordinates are rounded by the shift amount per rotation, as set in
parameter No. 1260. This can prevent coordinates for the rotation axis
from overflowing. Displayed values for relative coordinates are also
rounded by the angle corresponding to one rotation when parameter
RRLx (No. 1008#2) is set to 1. The roll-over function is enabled by
setting parameter ROAx (No. 1008#0) to 1.
For an absolute command, the coordinates after the tool has moved are
values rounded by the angle corresponding to one rotation set in
parameter No. 1260.
The tool moves in the direction in which the final coordinates are
closest when parameter RABx (No. 1008#1) is set to 0. For an
incremental command, the tool moves the angle specified in the
command.
If the rotation axis control function is used together with an absolute
command issued for an rotation axis, the axis rotation direction and
the coordinates of the end point are determined according to,
respectively, the algebraic sign and absolute value of a value specified
in the absolute command. The function is enabled by selecting a
roll-over function for the rotation axis (parameter ROAx (No. 1008#0)
= 1). If the parameter RAAx (No. 1007#3) is 1, issuing an absolute
command for a rotation axis with the roll-over function selected
causes the axis rotation direction and the coordinates of the end point
to match, respectively, the algebraic sign and absolute value of a value
specified in the absolute command. If the parameter RAAx (No.
1008#3) is 0, the axis rotation direction and the coordinates of the end
point are caused to match the setting of the parameter RABx (No.
1008#1). (The rotation axis control function is an option.)
For details of rotary axis control, see the section on “rotary axis
control” in this manual.
