• Transfer Position Data
• Calc Axis Move
• Calc Axis Move by Multipoint
Additional Information
The settings for the machine setting processing item can be referenced from other scenes.
The machine setting processing item can be registered only in one scene group, but it can be
referenced from other the scenes. This enables central management of the external device set-
tings.
Settings for the Calibration To Execute
Add the following Calibration processing items to the flow.
l
Vision Master Calibration
This processing item calculates the axis movement that is necessary to perform the most accurate
calibration within the range of movement of the external device.
This routine is performed repeatedly to create very precise calibration parameters: Output the
calculated axis movement to the PLC, the PLC moves the external device, the PLC sends a
measurement command to the FH/FHV series Controller.
Reference the Calibration Data Reference processing item to access the calibration parameters
that were created.
Refer to Vision Master Calibration of the Vision System FH/FHV Series Processing Item Function
Reference Manual (Cat. No. Z341).
Precautions for Correct Use
If you are using the measurement results of the Sensor Controller to operate an external de-
vice, make sure the movement is within the range of the movement of the external device be-
fore you implement the move.
Additional Information
The Vision Master Calibration processing item has the following advantages over PLC Master
Calibration processing item.
• There is no need for trial and error with the order of movements or axis movement, even with
complicated external devices, such as UVW stages.
The order of movement of the workpiece during calibration and the axis movement of the
external device that corresponds to each movement are automatically calculated.
• Even if you change the calibration conditions, you do not have to change the PLC ladder pro-
gramming.
If you add more sampling points for better precision, or if you reduce the number of sampling
points to shorten the calibration time, you can still use the ladder programming as is.
• In conjunction with calibration, you can also calculate the parameters for distortion correction
at the same time.
This allows you to align positions with even greater accuracy without doing any extra work.
