5.13.2 13-1* Comparators
Comparators are used for comparing continuous variables (that is output frequency, output current, analog input, and so on) to
fixed preset values.

Illustration 79: Comparators
There are digital values that are compared to fixed time values. See the explanation in parameter 13-10 Comparator Operand. Com-
parators are evaluated once in each scan interval. Use the result (true or false) directly. All parameters in this parameter group are
array parameters with index 0–9. Select index 0 to program comparator 0, select index 1 to program comparator 1, and so on.

Default value: Size related
Parameter type: Option, Array [10]
Setup: 2 setups
Conversion index: -
Data type: Uint8
Change during operation: True
Options [1] Reference % to [31] Counter B are variables which are compared based on their values. Options [50] FALSE to [186] Drive in
auto mode are digital values (true/false) where the comparison is based on the amount of time during which they are set to true or
false. See parameter 13-11 Comparator Operator.
