MACHINE PARAMETERS
SOFT: V02.2X
General machine parameters
MAXFOVR (P18)
Indicates the maximum value of the feedrate override % applicable to the programmed feedrate.
From the operator panel switch, it may be varied between 0% and 120% and from the PLC, DNC
or by program between 0% and 255%.
CIRINLIM (P19)
Indicates the maximum angular feedrate value for circular interpolations.
This limitation prevents circular interpolations resulting in polygons instead of arcs when the radius
is very small. The CNC adjusts the angular feedrate in order not to exceed the selected maximum
angular feedrate.
CIRINERR (P20)
Indicates the maximum error allowed when calculating the end point of an arc.
From the programmed path, the CNC will calculate the radius for both the starting point and end
point of the arc. Although both of them should be "exactly" the same, This parameter allows a certain
calculation tolerance by establishing the maximum difference between these two radii.
PORGMOVE (P21)
Indicates whether the CNC assumes or not as the new polar coordinate origin the center of the last
G02 or G03 programmed.
BLOCKDLY (P22)
It indicates the delay between motion blocks when operating in G7 (square corner).
This dwell can be very useful when some devices have to activated after the execution of each block.
Possible values
Integer numbers between 0 and 255.
Default value: 120
Possible values
Integer numbers between 0 and 65535.
Default value: 0 (it is not limited)
Sample
If "CIRINLIN" = 1500 and an arc of a radius = 0.5mm at F=10000mm/min.
The theoretical angular speed is:
10000 mm/min / 0.5 mm = 20000 min
-1
But, since the speed was limited to 1500, the CNC adjusts the feedrate in the following manner:
Feedrate to be applied = 1500 x 0.5 = 750 mm/min.
Possible values
Between 0.0001 and 99999.9999 millimeters.
Between 0.00001 and 3937.00787 inches.
Default value: 0.01 mm.
Value Meaning
YES It assumes the arc center.
EZ It is not affected by G02 and G03.
Default value: EZ
Possible values
Integers between 0 and 65535 ms.
Default value: 0 (there is no delay)
