3.9.1 13-** Prog. Features
Smart Logic Control (SLC) is 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 in pairs. This
means that when [0] event is fulfilled (attains the value
TRUE), [0] action is executed. After this, the conditions of
[1] event is evaluated and if evaluated TRUE, [1] action is
executed and so on. Only one 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. This means that when the SLC starts,
it evaluates [0] event (and only [0] event) each scan interval.
Only when [0] event is evaluated TRUE, the SLC executes
[0] action and start evaluating [1] event. 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 [0] event/[0] action.

Starting and stopping the SLC
Starting and stopping the SLC can be done by selecting [1]
On or [0] Off in 13-00 SL Controller Mode. The SLC always
starts in state 0 (where it evaluates [0] event). The SLC
starts when the Start Event (defined in 13-01 Start Event) is
evaluated as TRUE (provided that [1] On 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 [1] On to enable the Smart Logic Control to
start when a start command is present, e.g. via a
digital input. Select [0] Off 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 The motor current is outside the range
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 exceeds 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.
[25] Comparator 3 Use the result of comparator 3 in the
logic rule.
[26] Logic rule 0 Use the result of logic rule 0 in the
logic rule.
