[Data type] Bit
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.
8250
Axis number used for B–axis control
[Data type] Byte
[Valid data range] 1 to number of controlled axes
This parameter sets which axis is to be used for B–axis control.
Example of setting:
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.
8251
M code (G101) for specifying the start of first program operation
8252
M code (G102) for specifying the start of second program operation
8253
M code (G103) for specifying the start of third program operation
[Data type] 2–word
[Valid data range] 6 to 99999999
These parameters set M codes for starting previously registered B–axis
operation programs. M codes (such as M30, M98, and M99), already
used for other purposes, cannot be set.
8257
T code number for tool offset cancellation
[Data type] Byte
[Valid data range] 0 to 90
This parameter sets a T code number for tool offset cancellation. When
a T code from (setting + 1) to (setting + 9) is specified, tool offset is
specified.
