2.3.2 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.
2.3.4.1 ROTARY AXIS (A, B OR C AXIS)
The rotary axis is defined as follows.

2.3.3 SIMULTANEOUSLY CONTROLLABLE AXES OF
FOUR-AXIS
Table 2. 6 shows simultaneously controllable
axes.
Table 2.6 Simultaneously Controllable Axes of
Four-axis Control
B axis Rotary axis parallel to Y-axis
C axis 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 ” )
