13-1* Comparators
"
Used for comparing continuous variables (i.e. output
frequency, output current, analog input etc.) with
a fixed preset value. Comparators are evaluated
once in each scan interval. You can 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 parameters with
index 0-3. Select index 0 to program Comparator
0, index 1 to program Comparator 1, and so on.
