Parameters
13-10 Comparator Operand
Array [6]
Option: Function:
Select the variable to be monitored by
the comparator.
[0] Disabled
*
[1] Reference
[2] Feedback
[3] Motor speed
[4] Motor Current
[6] Motor power
[7] Motor voltage
[12] Analog input AI53
[13] Analog input AI54
[20] Alarm number

[31] Counter B
13-11 Comparator Operator
Array [6]
Option: Function:
[0] Less Than (<) Select [0] < for the result of the evaluation
to be TRUE, when the variable selected in
parameter 13-10 Comparator Operand is
smaller than the fixed value in
parameter 13-12 Comparator Value. The
result is FALSE, if the variable selected in
parameter 13-10 Comparator Operand is
greater than the fixed value in
parameter 13-12 Comparator Value.
[1] Approx.Equal Select [1] ≈ for the result of the evaluation
(~) to be TRUE, when the variable selected in
*
parameter 13-10 Comparator Operand is
approximately equal to the fixed value in
parameter 13-12 Comparator Value.
[2] Greater Than Select [2] > for the inverse logic of option
(>) [0] <.
13-12 Comparator Value
Array [6]
Range: Function:
0 [-9999 - Enter the 'trigger level' for the variable that
*
9999 ] is monitored by this comparator. This is an
array parameter containing comparator
values 0 to 5.
4.9.4 13-2* Timers
Use the result (TRUE or FALSE) from timers directly to
define an event (see parameter 13-51 SL Controller Event), or
as boolean input in a logic rule (see parameter 13-40 Logic
Rule Boolean 1, parameter 13-42 Logic Rule Boolean 2 or
parameter 13-44 Logic Rule Boolean 3). A timer is only

FALSE when started by an action (i.e. [29] Start timer 1)
until the timer value entered in this parameter is elapsed.
Then it becomes TRUE again.
All parameters in this parameter group are array
parameters with index 0 to 2. Select index 0 to program
Timer 0, select index 1 to program Timer 1, and so on.

4.9.5 13-4* Logic Rules
Combine up to 3 boolean inputs (TRUE/FALSE inputs) from
timers, comparators, digital inputs, status bits and events
using the logical operators AND, OR, and NOT. Select
boolean inputs for the calculation in parameter 13-40 Logic
Rule Boolean 1, parameter 13-42 Logic Rule Boolean 2 and
parameter 13-44 Logic Rule Boolean 3. Define the operators
used to logically combine the selected inputs in
parameter 13-41 Logic Rule Operator 1 and
parameter 13-43 Logic Rule Operator 2.

Priority of calculation
The results of parameter 13-40 Logic Rule Boolean 1,
parameter 13-41 Logic Rule Operator 1 and
parameter 13-42 Logic Rule Boolean 2 are calculated first.
The outcome (TRUE/FALSE) of this calculation is combined
with the settings of parameter 13-43 Logic Rule Operator 2
and parameter 13-44 Logic Rule Boolean 3, yielding the final
result (TRUE/FALSE) of the logic rule.

MG03N102 - Rev. 2013-12-02
Function:
Enter the value to define the duration of the
FALSE output from the programmed timer. A
timer is only FALSE if it is started by an action
(see 13-52 SL Controller Action [29-31] and
13-52 SL Controller Action [70-74] Start timer X)
and until the timer value has elapsed. Array
parameter containing timers 0 to 7.
