17.2.1 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 default 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 a 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 channelspecific PLC interface for auxiliary
functions (DB21, ... DBB158 to 193).
