17.3 Feedrate FA for positioning axes
Syntax
FA[<positioning axis>] = <feedrate value>
Functionality
The velocity of a positioning axis is programmed with axisspecific feedrate FA.
• Effectiveness: Modal
• Special points to be noted
- No more than 5 axis-specific feedreates can be programmed in each part program block.
- The feedrate is always G94.
- If no axial feedrate FA is programmed, the axial default:
MD32060 $MA_POS_AX_VELO (initial setting for positioning axis velocity) takes effect.
Parameter: Positioning axis
• Value range: Identifier of channel axes
MD20080 $MC_AXCONF_CHANAX_NAME_TAB
Parameter: Feed value
• Value range
0.001...999,999.999 mm/min, degrees/min or 0.001, ...39 999,9999 inch/min

• NC/PLC interface (channel-specific)
The feedrate is output at the channel-specific NC/PLC interface:
DB21, ... DBB158 - DBB193

of positioning axis, etc.) see:

• NC/PLC interface (axis-specific)
The feed value is output at the axis-specific NC/PLC interface:
