The new CONFIGURATORTM software simplifies the
setup and configuration of the STAC6. Click on the icon
representing the aspect of the drive that needs changing
and an intuitive dialog box will open. Configuration data
for recommended motors is available from a drop down
menu. The Configurator also allows the user to create a
custom motor configuration.
