Programmable feedrate override (OVR, OVRRAP, OVRA)

Function
The velocity of path/positioning axes and spindles can be modified in the NC program.

7.6 Programmable feedrate override (OVR, OVRRAP, OVRA)
Feedrate modification for path feedrate F
Feedrate modification for rapid traverse velocity
Feedrate modification for positioning feedrate FA or for spindle
speed S
Axis identifier (positioning or geometry axis)
Spindle identifier
SPI(<n>) and S<n> are identical in terms of function.
Spindle number
<n>:
Note:
SPI converts spindle numbers into axis identifiers. The transfer
parameter (<n>) must contain a valid spindle number.
Feedrate modification in percent
The value refers to or is combined with the feedrate override set on
the machine control panel.
Range of values: ... 200%, integers
Note:
With path and rapid traverse override, the maximum velocities set
in the machine data are not overshot.
