3.9.1 13-** Prog. Features
Smart Logic Control (SLC) is essentially a sequence of user
defined actions (see
13-52 SL Controller Action [x]) executed
by the SLC when the associated user defined event (see
13-51 SL Controller Event [x]) is evaluated as TRUE by the SLC.
Events and actions are each numbered and linked together
in pairs. This means that when event [0] is fulfilled (attains the
value TRUE), action [0] is executed. After this, the conditions
of event [1] will be evaluated and if evaluated TRUE, action [1]
will be executed and so on. Only one event will be 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 will be evaluated. This means that when the SLC
starts, it evaluates event [0] (and only event [0]) each scan
interval. Only when event [0] is evaluated TRUE, will the SLC
execute action [0] and start evaluating event [1]. It is possible
to programme from 1 to 20 events and actions . When the last
event / action have been executed, the sequence starts over
again from event [0]/ action [0].

Illustration 3.1 Example with three event/actions
Starting and stopping the SLC:
Starting and stopping the SLC can be done by selecting
On
[1] or Off [0] in 13-00 SL Controller Mode . The SLC always starts
in state 0 (where it evaluates event [0]). The SLC starts when
the Start Event (defined in 13-01 Start Event ) is evaluated as
TRUE (provided that On [1] is selected in 13-00 SL Controller
Mode ). The SLC stops when the Stop Event ( 13-02 Stop Event )
is TRUE. 13-03 Reset SLC resets all SLC parameters and starts
programming from scratch.
3.9.2 13-0* SLC Settings
Use the SLC settings to activate, deactivate and reset the
Smart Logic Control sequence. The logic functions and
comparators are always running in the background, which
opens for separate control of digital inputs and outputs. .
13-00 SL Controller Mode
Option: Function:
Select On [1] to enable the Smart Logic Control to start
when a start command is present, e.g. via a digital input.
Select Off [0] to disable the Smart Logic Control.
[0] Off Disables the Smart Logic Controller.
[1] On Enables the Smart Logic Controller.
13-01 Start Event
Option: Function:
Select the boolean (TRUE or FALSE) input
to activate Smart Logic Control.
[0] False Enters the fixed value of FALSE in the
logic rule.
[1] True Enters the fixed value TRUE in the logic
rule.
[2] Running The motor is running.
[3] In range Motor runs within programmed current
ranges (
4-50 Warning Current Low and
4-51 Warning Current High )
[4] On reference The motor runs at reference speed.
[7] Out of current
range The motor current is outside the range
set in
4-18 Current Limit .
[8] Below I low The motor current is lower than set in
4-50 Warning Current Low .
[9] Above I high The motor current is higher than set in
4-51 Warning Current High .
[16] Thermal warning The thermal warning turns on when the
temperature exeeds the limit in the
motor, the frequency converter or the
thermistor.
[17] Mains out of
range
[18] Reversing The frequency converter is reversing.
[19] Warning A warning is present.
[20] Alarm (trip) An alarm is present.
[21] Alarm (trip lock) A trip lock alarm is present.
[22] Comparator 0 Use the result of comparator 0 in the
logic rule.
[23] Comparator 1 Use the result of comparator 1 in the
logic rule.
[24] Comparator 2 Use the result of comparator 2 in the
logic rule.
