7.5 Feedrate for positioning axes/spindles (FA, FPR, FPRAON, FPRAOF)

7.5 Feedrate for positioning axes/spindles (FA, FPR, FPRAON,
FPRAOF)
Function
Positioning axes such as workpiece transport systems, tool turrets and end supports are
traversed independently of path and synchronized axes. A separate feedrate is therefore
defined for each positioning axis.
A separate axial feedrate can also be programmed for spindles.
It is also possible to derive the revolutional feedrate for path and synchronized axes or for
individual positioning axes/spindles from another rotary axis or spindle.
Syntax
Feedrate for positioning axis:
FA[<axis>]=...
Axis feedrate for spindle:
FA[SPI(<n>)]=...
FA[S<n>]=...
Derive revolutional feedrate for path/synchronized axes:
FPR (<rotary axis>)
FPR(SPI(<n>))
FPR(S<n>)
Derive rotational feedrate for positioning axes/spindles:
FPRAON(<axis>,<rotary axis>)
FPRAON(<axis>,SPI(<n>))
FPRAON(<axis>,S<n>)
FPRAON(SPI(<n>),<rotary axis>)
FPRAON(S<n>,<rotary axis>)
FPRAON(SPI(<n>),SPI(<n>))
FPRAON(S<n>,S<n>)
FPRAOF(<axis>,SPI(<n>), etc.)
FPRAOF(<axis>,S<n>, etc.)
