[Cause]
There are invalid settings in the pre-grayscale settings. In particular, for the workpiece parameters (size), if the virtual tray cells are too close, calling PKCSGENVRTRY.PC may cause a determination that the reference workpiece collides with an arranged workpiece, issuing an alarm.
[Countermeasure]
Check the pre-grouping settings. For the workpiece workpiece parameters (size), particularly check whether the virtual tray cells are too close.
