Table 14.2 Conditions for Local/Remote Reference Activation
Parameter 1-00 Configuration Mode determines what kind
of application control principle (for example, speed, torque,
or process control) is used when the remote reference is
active.
Parameter 1-05 Local Mode Configuration determines
the kind of application control principle that is used when
the local reference is active. One of them is always active,
but both cannot be active at the same time.
14.8 Smart Logic Controller
Smart logic control (SLC) is a sequence of user-defined
actions (see
parameter 13-52 SL Controller Action [x])
executed by the SLC when the associated user-defined
event (see
parameter 13-51 SL Controller Event [x]) is
evaluated as true by the SLC.
The condition for an event can be a particular status or
when the output from a logic rule or a comparator
operand becomes true. This condition leads to an
associated action as shown in

Illustration 14.8 Current Control Status/Event and Action
Events and actions are each numbered and linked together
in pairs (states). For example, when
[0] event is fulfilled
(attains the value true), [0] action is executed. Afterwards,
the conditions of [1] event are evaluated and if evaluated
true, [1] action is executed, and so on. Only 1 event is
evaluated at any time. If an event is evaluated as false,
nothing happens in the SLC during the current scan
interval and no other events are evaluated. When the SLC
starts, it evaluates only
[0] event each scan interval. Only
when [0] event is evaluated true, the SLC executes [0]
action and starts evaluating [1] event . It is possible to
program 1–20 events and actions .
When the last event / action has been executed, the
sequence starts over again from [0] event / [0] action .
