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)
Output to PLC
The feedrate value can be output to the the PLC:
● To the channel-specific NC/PLC interface via:
DB21, ... DBB158 - DBB193
● To the axis-specific NC/PLC interface via:
DB31, ... DBB78 - DBB81
The output time is specified with the machine data:
