Writing the User Program
Vxxx+2 = maximum correction value in IUs. (positive values only)
The difference between Vxxx+0 and Vxxx+1 can be limited to
a maximum measurement with these variable.
Vxxx+3 = Beginning of search in IUs
(measured from the start position of the command)
Vxxx+4 = End of search in IUs
(measured from the start position of the command)
Vxxx+4 = 000 (no monitoring of search distance)
Vxxx+5 = target instruction, when end of search is exceeded
Vxxx+6
(Reserved)
Mode:
0 = disabling the functionality "Raster detection"
1 = automatic correction with following movement
The difference between the desired and the measured distance is
output. The feed length of the next feed command is corrected by
this value. To avoid a large correction, and therefore a movement
which is too small, a maximum correction value can be set in the
variable Vxxx+2.
The beginning and end of the search can be set in variables Vxxx+3
and Vxxx+4. If there is no raster signal in this area, the program
branches to the instruction number set in variable Vxxx+5. The
positioning operation is completed. If search monitoring is not
enabled and no raster signal is detected, the next positioning
movement is executed without correction.
2 = automatic correction in the current positioning operation
this function corresponds to Assignment 1. The correction is
performed immediately after detection of the raster signal.
3 = Raster position detection
This function corresponds to Assignment 1. However, no correction
is made. The information is entered in variable Vxxx+0 and marker
flag M2.xx.4. This data is cleared only when the next positioning
command is started.
Note:
The execution of the SRP command can take up to 100ms.
