H.3 Link Assignment
Start the MPE720 to open the Link Assignment Tab bed Page in the MECHATROLINK Transmission Definition
Window. Make the settings as shown in the table below in the station where you want to allocate a wild card servo.
SVB Module operates as though the actual object is true, despite the setting. If “*****SERVO” is set in place of
“SGDS-1” for example, the SVB Module recognizes it as SGDS and operates accordingly.
