H3-11/H3-12: Terminal A2 Gain/Bias Setting
Parameter H3-11 sets the level of the selected input value that is equal to 10 Vdc/20 mA
input at terminal A2 (Gain).
Parameter H3-12 sets the level of the selected input value that is equal to 0 Vdc/4 mA/0 mA
input at terminal A2.
Both can be used to adjust the analog input A2 characteristics. The setting works in the same
way as parameters H3-03/04 for analog input A1.
■
H3-13: Analog Input Filter Time Constant
Parameter H3-12 sets the time constant for a first order filter that will be applied to both
analog inputs A1 and A2.
An analog input filter can be used to prevent erratic drive control when a “noisy” analog
reference is used. The drive operation becomes more stable the longer the time programmed,
but it becomes less responsive to rapidly changing analog signals.

Multi-Function Analog Input Terminal Settings
This section describes the various functions that can be assigned to terminal A1 and A2 by
setting H3-02 and H3-10.
Note:
Keep in mind, that the scaling of all input functions depends on the gain and bias settings for the
analog inputs. Set these to appropriate values when selecting and adjusting analog input
functions.
