Applications In this section a few of many applications are described, as well as
why the particular control method was selected. For example,
tumbler drum is described using a soft start feature. We will then
“build” upon this application to describe how the SMC-2 controller
options can be used to improve the tumbler drum performance and
productivity.
Illustrations are included to help identify the particular application.
Motor ratings are specified but this may vary in other typical
applications.
