COF
[Data type] Bit
COF For tool post 1 and tool post 2 (under two–path control):
0 : A separate B–axis offset value is set.
1 : A common B–axis offset value is set.
BPF For feed per revolution with the B–axis control function, the parameters
for the unit of PMC feedrate data specification, FR1 and FR2 (bits 6 and 7
of parameter No. 8002) are:
0 : Valid.
1 : Invalid.

Axis number used for B–axis control
[Data type] Byte
[Valid data range] 1 to number of controlled axes (in one–path control)
11 to ((number of controlled axes for path 1) + 10), or
21 to ((number of controlled axes for path 2) + 20) (in two–path control)
This parameter sets which axis is to be used for B–axis control.
In one–path control, set the controlled axis number of a selected B–axis.
In two–path control, set the axis number, used for B–axis control on path
1, added to 10 when a path 1 axis is used.
Set an axis number, used for B–axis control on path 2, added to 20 when
a path 2 axis is used.
Example of setting:
(1) For one–path control
When the fourth axis is controlled as the B–axis, set 4 in this
parameter. Furthermore, specify a DI/DO number to be used for the
fourth axis in parameter No.8010.
(2) For two–path control
(a) When B–axis control is applied to path 1 only
When the fourth axis of path 1 is controlled as the B–axis, set 14
with this parameter. Furthermore, specify the DI/DO number to be
used for the fourth axis with parameter No.8010 for path 1.
(b) When B–axis control is applied to path 2 only
When the fourth axis on path 2 is controlled as the B–axis, set 24
with this parameter. Furthermore, specify a DI/DO number to be
used for the fourth axis in parameter No.8010 for path 2.
(c) When B–axis control is applied separately to path 1 and path 2
Make the settings described in (a) and (b) above.
(d) When B–axis control is simultaneously applied to both path 1 and
path 2
When the fourth axis for path 1 is controlled as the common B–
axis, set 14 with this parameter for both path 1 and path 2. Fur-
thermore, specify a DI/DO number to be used for the fourth axis
in parameter No.8010 for path 1.
