Machining feedrate.

MAXFEED
Maximum machining feedrate on the tool path.
Possible values: From 0 to 500000.0000 mm/min / from 0 to 19685.03937 inch/min.
Default value: 0.
Associated variable: (V.)[ch].MPG.MAXFEED
This parameter sets the maximum machining feedrate (movements in G01/G02/G03) along
the path; when set to ·0·, the feedrate is not limited This parameter cannot be set with a value
higher than that of parameter G00FEED.
When trying to exceed the maximum feedrate via part-program, via PLC or from the operator
panel, the CNC limits the feedrate to the maximum value set in MAXFEED without showing
any error message or warning.
If the machining feedrate is not limited, the CNC assumes for all the movements the one set
in machine parameter G00FEED as the maximum feedrate.
How to limit temporarily the maximum feedrate via PLC
The PLC has the variable (V.)[ch].PLC.G00FEED that may be used to limit the feedrate in
the channel for any type of movement (G00, G01, etc). This variable limits the feedrate of
the path and affects all the axes whether they move interpolated or one axis at a time.
The CNC assumes the change immediately and the change stays active until the variable
takes a value of ·0· restoring the limits set by machine parameters.
DEFAULTFEED
Assume MAXFEED for movements in G1/G2/G3 without active
feedrate.
Possible values: Yes / No.
Default value: No.
Associated variable: (V.)[ch].MPG.DEFAULTFEED
This parameter sets whether or not the axes move at the feedrate set in MAXFEED when
programming a movement in G01/G02/G03 without programming the feedrate. If this
parameter is set to ·No·, the CNC will issue an error message when programming a
movement in G01/G02/G03 without programming the feedrate.
The CNC takes this parameter into account when MAXFEED has been set with a value other
than ·0·.
