Machine parameters for the axes. Work sets.
ADJUSTMENT OF RAPID TRAVERSE G00 AND MAXIMUM
SPEED.
G00FEED
Feedrate in G00.
Parameter valid for linear and rotary axes and spindles.
Parameter valid for analog drive, Sercos and simulated.
Possible values: From 0 to 500000.0000 mm/min / from 0 to 36000000 degrees/min / from 0 to
19685.03937 inch/min / from 0 to 100000.0000 rpm.
Default value: 10000.0000 mm/min / 1080000 degrees/min / 393.70079 inch/min / 3000.0000 rpm.
Associated variable: (V.)[ch].MPA.G00FEED[set].xn
Rapid positioning (traverse, G00) are always carried out at the maximum speed possible.
The one indicated by G00FEED.
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.
MAXFEED
Maximum axis machining feedrate.
Parameter valid for linear and rotary axes and spindles.
Parameter valid for analog drive, Sercos and simulated.
Possible values: From 0 to 500000.0000 mm/min / from 0 to 500000.0000 degrees/min / from 0 to
19685.03937 inch/min / from 0 to 1388.8889 rpm.
Default value: 0.
Associated variable: (V.)[ch].MPA.MAXFEED[set].xn
This parameter sets the maximum machining feedrate (movements in G01/G02/G03) of the
axis; when set to ·0·, the feedrate is not limited This parameter cannot be set with a value
higher than that of parameter G00FEED.
If REVEHYST= 0.0005 mm, the CNC will not activate the compensation in reversals
occurring after the first one as long as the axis position does not change (vary) at least in
the amount set by this parameter, taking as reference the position it occupied in the first
position command reversing order.
In other words, if the CNC receives a command (order) to reverse when the position
command has only changed 0.0002 mm from the position where the first reversal command
took place, the CNC does not apply the compensation (the value set in REVEHYST has
not been exceeded) and it simply reverses the moving direction.
Only when the position command variation reaches 0.0005 mm, the CNC will apply the
compensation. After applying a compensation, the CNC will take the new order to reverse
as a new reference to evaluate the position variation and determine when the value set in
parameter REVEHYST has been reached again and start compensating again.
