When the pusher has finished pushing the plate onto the transfer table, the
edge of the plate should be a fixed distance from the pusher Y-axis stepper
position, as measured by the inductive sensors on the pusher vacuum towers.
However, due to mechanical variation, this distance may vary from machine to
machine. Therefore, this NVS parameter allows adjustment to the plate edge
position to compensate.
Set this parameter if the plate edge detection process during a load suspends
with error 47639 "Plate not positioned correctly on the transfer table." even
though the plate is squarely on the table in the correct place.
Look for the text "Plate is on the transfer table with edge A and B mm, ideal edge = C mm"
(displayed at service verbosity) to help calculate the correct adjustment value.
Set this parameter to ((A + B) / 2) - C.
A positive value increases the stepper position of the ideal plate edge.
A negative value decreases this position.
This parameter is available.
0.000 [mm]
Please issue the appropriate monitor command to determine this parameter's minimum and maximum values.
