Note:
In a feedrate-specified move, if the move time for any non-feedrate axis, computed
as axis distance divided by Isx86, is greater than the move time for the feedrate
axes, computed as the vector distance divided by the feedrate, Turbo PMAC will
use the move time for the non-feedrate axis instead.
as axis distance divided by Isx86, is greater than the move time for the feedrate
axes, computed as the vector distance divided by the feedrate, Turbo PMAC will
use the move time for the non-feedrate axis instead.
The FRAX command without arguments causes all axes in the coordinate system to be feedrate axes in
subsequent move commands. The FRAX command with arguments causes the specified axes to be
feedrate axes, and all axes not specified to be non-feedrate axes, in subsequent move commands.

If no motion program buffer is open when this command is sent to Turbo PMAC, it will be executed as an
on-line coordinate system command.

Turbo PMAC interprets this statement as a CALL 10n0.({data’}*1000) command, where n is the
hundreds’digit of {data}, and {data’} is the value of {data} without the hundred’s digit (modulo
100 in mathematical terms). That is, this statement causes a jump (with return) to motion program 10n0,
and the specified line label. (Usually, programs 10n0 are used to implement the preparatory codes as the
system designer sees fit.) The value of {data’} can be from 0.0 to 99.999, corresponding to line labels
N0 to N99999.
