5.7 H: Terminal Functions
Setting 2: 4 to 20 mA
The input level is 4 to 20 mA. Negative input values by negative bias or gain settings will be limited to 0%.
Setting 3: 0 to 20 mA
The input level is 0 to 20 mA. Negative input values by negative bias or gain settings will be limited to 0%.
■ H3-10: Terminal A2 Function Selection
Determines the function assigned to analog input terminal A2.

H3-11, H3-12: Terminal A2 Gain and Bias Setting
■
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.
Both can be used 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.

H3-12
■ H3-13: Analog Input Filter Time 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 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.
No.
H3-13
H3-14: Analog Input Terminal Enable Selection
■
When one of the multi-function digital input parameters is set for "Analog terminal input selection" (H1- = C), the
value set to H3-14 determines which of the analog input terminals will be enabled or disabled when the input is closed.
All analog input terminals will be enabled all of the time if H1- is not set to C. The terminals other than the one set as
the target are not influenced by input signals.
No.
H3-14
Setting 1: A1 only enabled
Setting 2: A2 only enabled
Setting 3: A1 and A2 only enabled
Setting 4: A3 only enabled
Setting 5: A1 and A3 only enabled
Setting 6: A2 and A3 only enabled
Setting 7: All analog input terminals enabled
H3-16 to H3-18 Terminal A1/A2/A3 Offset
■
Parameters H3-16 to H3-18 set the offset level of the selected input value to terminal A1, A2 or A3 that is equal to 0 Vdc
input. These parameters rarely need adjustment.
