deactivated
FPRAOF AXIS: Axis for which

deactivated
FPR AXIS: Axis/spindle from
which the revolutional
feedrate is derived.
If no axis has been
programmed, the
revolutional feedrate is
derived from the master
spindle.
It is also possible to program a spindle instead of an axis: FPR(S1) or FPR(SPI(1))

Explanation
Feedrate per revolution axial ON: Axial
revolutional feedrate ON
Feedrate per revolution axial OFF: Axial
revolutional feedrate OFF
The revolutional feedrate can be deactivated for
several axes at once. You can program as
many axes as are permitted in a block.
Feedrate per revolution: selection of a rotary
axis or spindle from which the revolutional
feedrate of the path is derived if G95 is
programmed.
If no axis/spindle has been programmed, the
revolutional feedrate is derived from the master
spindle.
The setting made via FPR is modal.
