Position measurement processing item Measure the position of the alignment marks or the position of
a special feature of the workpiece from the image in Camera 0.
To output the actual coordinates of the position, set
Calibration on the Output parameter tab page to ON.
Set the workpiece in reference position and then set the refer-
ence position.

Calc Axis Move by Multipoint processing
item
Set the machine setting processing item to reference. Then set
the expressions for the position measurement processing
items, Reference XY and Measure XY in the Reference
position XY and Measurement position XY in the Calc Axis
Move by Multipoint processing item.
Before you execute the measurement, set the Current setting
with the position of the axis of the external device when the
measurement was performed.

Data output processing item
Depending on the communications method, register either
Data output or Fieldbus data output.
Send each Axis movement expression in the Calc Axis Move
by Multipoint processing item to the PLC.
Settings for Position Alignment
l
Transfer Position Data + Calc Axis Move
Use these settings to align the measured position and measured angle with the reference position
and reference angle.
The movement that is required to align each axis of the external device is calculated and output.
Refer to Transfer Position Data and Calc Axis Move in the Vision System FH/FHV Series
Processing Item Function Reference Manual (Cat. No. Z341).
l
Calc Axis Move by Multipoint
Use this setting to align more than one measured position with corresponding reference positions.
The movement that is required to align each axis of the external device is calculated and output.
Refer to Calc Axis Move by Multipoint in the Vision System FH/FHV Series Processing Item
Function Reference Manual (Cat. No. Z341).
