3.9.1 13-** Prog. Features
Smart Logic Control (SLC) is a sequence of user defined
actions (see
[x]) executed by the
SLC when the associated user defined
event
(see
[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
. The SLC always
starts in state 0 (where it evaluates
[0] event
). The SLC
starts when the Start Event (defined in
) is
evaluated as TRUE (provided that
[1] On
is selected in
). The SLC stops when the
Stop
Event
) is TRUE.
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 (
and
)
[4]
On reference
The motor runs at reference speed.
[7]
Out of current
range
The motor current is outside the range
set in
.
[8]
Below I low
The motor current is lower than set in
.
[9]
Above I high
The motor current is higher than set in
.
[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)

logic rule.
[26]
Logic rule 0
Use the result of logic rule 0 in the
logic rule.
