SIMULTANEOUSLY CONTROLLABLE AXES OF
THREE-AXIS CONTROL
Table 2. 5 shows simultaneously controllable
axes.
Table 2.5 Simultaneously Controllable Axes of
Three-axis Control
(1) The
axis represents any one of axes A, B, C,
U, V or W, selected as the 4th axis.
(2) Circular arc plane is determined according to
the currently effective G codes for plane desig-
n a t i o n
to
. For details, refer to
2.9.4, “ CIRCULAR INTERPOLATION
on page 22.
(3) For circular interpolation axis
any one of
linear axes U, V , and W should be designated.
2.3.4 4TH
AXIS
An additional 4th axis can be incorporated. In
this manual, the 4th axis is referred to as
axis, and represents any of the 6 axes, A, B,
U, V and W.
Address. is specified
parameter
#6023.

Table 2. 6 shows simultaneously controllable
axes.

Rotary axis parallel to Z-axis
N o t e :
In this manual, any one of the three
axes, A, B and C, is referred to as
B-axis .
The unit of output increment and input increment
for B-axis is “deg. instead of “mm” used with
linear axes.
For the other respects, the treat-
ments are the same as those in mm.
(Metric
system)
Even when inch system is selected by parameter,
the values for the B- axis remains “deg. “ unit.
The control does not convert B-axis coordinate
commands.
However, feedrate command F is
converted. (Refer to 2.9.3. “ LINEAR INTERPO-
L A T I O N ” )
