Feedrate For Positioning Axes (Fa) - Siemens SINUMERIK 840D Function Manual

5.3 Feedrate for positioning axes (FA)

5.3 Feedrate for positioning axes (FA)
Function
The velocity of a positioning axis is programmed with axis-specific feedrate FA.
FA is modal.
The feedrate is always G94.
Note
The maximum axis velocity (MD32000 $MA_MAX_AX_VELO) is not exceeded.
Programming
No more than five axis-specific feedrates can be programmed in each part program block.
Syntax:
FA[<positioning axis>] = <feedrate value>
<positioning axis>:
<feedrate value>:
Default setting
If no axial feedrate FA is programmed, the axial default setting is applied:
MD32060 $MA_POS_AX_VELO (initial setting for positioning axis velocity)
156
$PA_FGROUP[<axis>]
$P_FGROUP_MASK
Returns the value "1" if the specified axis affects the path
velocity by means of the basic setting or through FGROUP
programming. Otherwise, the variable returns the value
"0".
Returns a bit key of the channel axes programmed
with FGROUP which are to affect the path velocity.
