5.3 Description of Function Codes 5.3.1 F codes (Fundamental functions)
When operating unipolar analog input as bipolar
(terminal [12] (C35 = 0), terminal [V2] (C45 = 0), terminal [C1] (C1 function) (C40 = 10, 11), terminal [C1] (V3
function) (C78 = 0))
By setting the bias value to a minus value, it is possible to obtain a negative reference frequency.
Example of frequency setting with terminal [V2] when -100 % is set to the bias value is shown in the diagram below.
Reference frequency
-100%
Reference frequency
+100 %
