Feedrate Parameters
Chapter 9
9-6
Function
Use this parameter to set a value for the first position of the Rapid Feedrate
Override switch (labeled F1 on the MTB panel). Enter a percent value for
this parameter. The value for the other three switch positions is determined
in PAL. The axis travels in normal rapid positioning (G00) mode at the
Rapid Feedrate for Positioning multiplied by the percent value entered here
when the Rapid Feedrate override switch is set to F1.
Axis Parameter
Number
All [67]
Range
0% to 100%
Notes
When a value of 0% is set for this parameter, the Rapid Feedrate for
Positioning is reduced to 0 and, in effect, places the control in “Feedhold.”
No axis motion takes place.
When the control powers up F1 is the default feedrate override on a
push-button MTB panel.
This parameter in no way relates to the single-digit “Feedrate for F1”
parameter.
This is a global parameter. The value set here applies to all axes.
