erminal A2 Gain and Bias Settin
Parameter H3-11 sets the level of the input value selected that is equal to 10 Vdc input or 20 mA input to terminal A2.
Parameter H3-12 sets the level of the input value selected that is equal to 0 V, 4 mA or 0 mA input at terminal A2.
Use both parameters to adjust the characteristics of the analog input signal to terminal A2. The setting works in the same way
as parameters H3-03 and H3-04 for analog input A1.

Analo Input Filter ime Constant
Parameter H3-13 sets the time constant for a first order filter that will be applied to the analog inputs.
An analog input filter prevents erratic drive control when using a "noisy" analog reference. Drive operation becomes more
stable as the programmed time becomes longer, but it also becomes less responsive to rapidly changing analog signals.
