2.1 2.1 Path feedrate F
2.1.1 General
Path feedrate F
The path feedrate represents the geometrical total of the velocity components in the
participating axes. It is therefore generated from the individual motions of the interpolating
axes.
The standard setting uses the axial velocities of the geometry axes which have been
programmed. The FGROUP command can be used to include other geometry and/or
synchronized axes in the calculation of the path feedrate.
The path feedrate F determines the machining speed and is observed in every type of
interpolation even where allowance is made for tool offsets. The value programmed under
the address F remains in the program until a new F value or a new type of feedrate is
programmed.

F value at PLC interface
The F value of the current path feedrate is always entered in the channel-specific PLC
interface for auxiliary functions (DB21, ... DBB158 to 193).
The related interface signals (modification signal, F value) are described in:
