LASER MACHINES 2
P807 Maximum sheetmetal deflection
This parameter is used when the sheetmetal tracing feature is active. It prevents
abrupt laser movements when detecting holes, objects, etc. while machining the
sheetmetal.
It indicates the maximum sheetmetal deflection value. It is always expressed in
microns regardless of the work-units being used.
Possible values: 0 thru 32000 microns.
If set to "0", the "sheetmetal tracing" feature will not be activated.
If the value assigned to this parameter is exceeded, the CNC will deactivate the
"sheetmetal tracing" feature and depending, on the operating mode, it will act as
follows:
* In the JOG mode, the CNC will display the following error of the Z axis.
* In the rest of the operating modes, the CNC will generate an external CYCLE
STOP executing the emergency subroutine if it has been programmed.
P808 Analog corresponding to maximum Z axis feedrate
It sets the analog voltage corresponding to the maximum Z axis feedrate when
executing special functions: M97 or M98 (sheetmetal tracing).
It is always defined in microns regardless of the work units being used.
Possible values: 0 to 32000 microns.
If set to "0", the maximum analog voltage value for the Z axis will be:
2.5mV.
Analog (mV.) = P806 x K1 x ————
64
If set to a value other than "0", the maximum analog voltage for the Z axis will
be:
2.5mV.
Analog (mV.) = P808 x K1 x ————
64
The proportional gain K1 of the Z axis is determined by machine parameter P314.
Example: Machine parameters: “P314”= 32 and “P806”= 2000.
The Z axis is controlled by a 10V-system providing 3000 mm/min and the Z
axis feedrate is to be limited to 300 mm/min.
Therefore, the Z axis analog voltage must be limited to 1V (10% of 10V).
This will give us the following value:
2.5mV.
1000 mV. = P808 x 32 x ———— ===> P808 = 800
