4.2.4 Teaching the wafer component positions
After wafer components run out during production and new components are supplied, you must teach their
positions using the procedures described below. Teaching must be performed in the specified order: "Angle
teach"
→
"Alignment teach"
→
"Pitch teach"
→
"Position teach".
The teach screens can be opened with the buttons on the "Tray Counter" screen that opens when you press the
[TrayCnt] button in the "Utility" group box on the Setup screen, or with the buttons on the "Wafer Information"
screen that opens when you press the [Wafer] button on the [Parts]-[Tray] screen.
