An error stop will be carried out if at least one of three conditions is below in agreement.
The error calculation method
1
（X shift value）
[Max Diff X(mm)] (*1) < |the PCB fiducial correction value X before mounting -
the PCB fiducial correction value X after mounting|
2
（Y shift value）
[Max Diff Y(mm)] (*1) < |the PCB fiducial correction value Y before mounting -
the PCB fiducial correction value Y after mounting|
3
（R shift value）
[Max Diff R(deg)] (*2) < |the PCB fiducial correction value R before mounting -
the PCB fiducial correction value R after mounting|

The timing which checks difference can be chosen from following three.
Diff Check Timing Explanation
1 AllBoard A difference check is certainly carried out for every 1 board
loading.
2 SwitchBoard After a board data is read, only one board carries out a
difference check. The board after the 2nd sheet does not
carry out a difference check.
3 AutoRun If the RUN button is pushed in a halt state or a reset state,
only one board will carry out a difference check. The board
after the 2nd sheet does not carry out a difference check.
In the board data to be mounted by two or more tables onto one board, PCB fiducial after
mounting is carried out on each table.
When a PCB fiducial recognition error occurs, a vision cursor Teach dialog is displayed.
This function operates effectively by carrying out teaching correctly on this screen.
After one table finishes mounting, its mount head will moves to the waiting position.

(1) After one table finishes mounting, its mount head moves to the waiting position.
(2) The table stays at the waiting position while the other one mounting and moving to its
waiting position.
(3) The table keeps staying at the waiting position until the other one finishes a PCB
fiducial recognition after mounting.
