13-10 Comparator Operand
Array [6]
Option: Function:
Linked to hand Auto , at the same time
as the LCP is in Hand On mode.
[181] Remote ref. active High when 3-13 Reference Site = [1]
Remote or [0] Linked to hand/auto ,
while the LCP is in Auto On mode.
[182] Start command High when there is an active start
command, and no stop command.
[183] Drive stopped A stop command (Jog, Stop, Qstop,
Coast) is issued – and not from the
SLC itself.
[185] Drive in hand
mode
High when the frequency converter is
in hand mode.
[186] Drive in auto
mode
High when the frequency converter is
in auto mode.
[187] Start command

13-11 Comparator Operator
Array [6]
Option: Function:
Select the operator to be used in the
comparison. This is an array parameter
containing comparator operators 0 to 5.
[0] < The result of the evaluation is TRUE, when
the variable selected in
13-10 Comparator
Operand is smaller than the fixed value in
13-12 Comparator Value . The result is FALSE,
if the variable selected in 13-10 Comparator
Operand is greater than the fixed value in
13-12 Comparator Value .
[1]
*
≈ (equal) The result of the evaluation is TRUE, when
the variable selected in
13-10 Comparator
Operand is approximately equal to the fixed
value in 13-12 Comparator Value .
[2] > Inverse logic of option < [0].
[5] TRUE longer
than..
[6] FALSE
longer than..

*
[-100000.000 -
100000.000 ] Enter the ‘trigger level’ for the
variable that is monitored by
this comtor. This is an array
parameter containing comtor
values 0 to 5.
6.10.4 13-1* RS Flip Flops
The Reset-Set Flip Flops hold the signal until set/reset.

Illustration 6.16
The two operators can be selected from a long list. As a
special case, the same digital input can be used as both
Set and Reset, making it possible to use the same digital
input as start/stop. The following settings can be used to
set up the same digital input as start/stop (example given
with DI32 but is not a requirement).
