Note1: In Cascade control, the LP2 lamp is lit while the Loop-2 parameter is displayed.
Set SC=2 when there are a lot of disturbances, and much hunting occurs.
Set SC=3 when SP is changed frequently. Hunting suppressing effect is smaller than that
of SC=2, however, responsiveness is good.
The Super function (SC=2 and 3) does not work in direct action.
