FC 300 Design Guide
Function:
Select Reset SLC [1] to reset all group 13 param-
eters (13-*) to default settings.
Select *Do not reset SLC [0] to retain the pro-
grammed settings in all group 13 parameters (13-
*).
13-1* Comparators
Comparators are used for comparing continuous
variables (i.e. output frequency, output current,
analog input etc.) with fixed preset values. Com-
parators are evaluated once in each scan interval.
Use the result (TRUE or FALSE) directly to define
an event (see par. 13-51), or as boolean input in
a logic rule (see par. 13-40, 13-42, or 13-44). All
parameters in this parameter group are array pa-
rameters with index 0 to 3. Select index 0 to pro-
gramme Comparator 0, select index 1 to pro-
gramme Comparator 1, and so on.

Function:
Select the variable to be monitored by the com-
parator.
*False [0] (default setting) enters the fixed value
of FALSE in the logic rule.
True [1]. enters the fixed value TRUE in the logic
rule.
