Feedrate related variables.
10.43 Feedrate related variables.
FEEDRATE ACTIVE IN THE CHANNEL.
(V.)[ch].G.FREAL
Variable that can only be read from the program, PLC and interface.
The variable returns the execution value; reading it interrupts block preparation.
Channel [ch]. Real feedrate on the tool path.
Use the oscilloscope to compare the real and theoretical feedrates along the path and detect
adjustment problems when both are different at specific points. Also, using variables
V.G.LINEN and V.G.BLKN, it is possible to associate these feedrate changes with the
program blocks or lines where they occur.
Syntax.
·ch· Channel number.
Remarks.
This variable takes into account the accelerations and decelerations of the machine. When
the axes are stopped, it returns a value of ·0· and when moving it returns the value
corresponding to the feedrate type G94/G95. On laser cutting machines, it is recommended
to use this variable so the laser power is proportional to the feedrate.
(V.)[ch].G.PATHFEED
Variable that can only be read from the program, PLC and interface.
The variable returns the execution value; reading it interrupts block preparation.
Theoretical feedrate on the tool path.
Use the oscilloscope to compare the real and theoretical feedrates along the path and detect
adjustment problems when both are different at specific points. Also, using variables
V.G.LINEN and V.G.BLKN, it is possible to associate these feedrate changes with the
program blocks or lines where they occur.
Syntax.
·ch· Channel number.
(V.)[ch].PLC.G00FEED
Variable that can be read and written from the PLC and read from the program and from the interface.
The variable returns the execution value; reading it interrupts block preparation.
Channel [ch]. Maximum feedrate permitted in the channel.
This variable may be used to limit any time, in real time, the maximum feedrate in the channel
for any type of movement (G00, G01, etc). The CNC assumes the change immediately and
stays active until the variable takes a value of ·0· restoring the limit set by machine parameter.
