• The data used for the configuration is displayed on the lower part of the M-MDS display when the configuration is completed.
(1) Continue to perform configuration following the instructions on the M-MDS screen.
(4) If manual configuration is performed using the As-Built data, write the coupling component characteristic value. (AWD) (See COUPLING COMPONENT CALIBRATION DATA WRITING.)
