3.9 Main Menu - Smart Logic - Group 13

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.
