Setting 2: 4 to 20 mA Current Input
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 Current Input
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.

No.
H3-10
<1> Default is 0 when b5-01 is set to 0.
Default is B when b5-01 is set to 1 or 3.

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.
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.
No.

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 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.
No.

H3-14: Analog Input Terminal Enable Selection
When one of the multi-function digital input parameters is set for "Analog input enable" (H1-oo = C), the value set to H3-14
determines which analog input terminals are enabled when the input is closed. All of the analog input terminals will be enabled
all of the time when H1-oo≠ C. The terminals not set as the target are not influenced by input signals.
No.

Setting 2: A2 Only Enabled
Setting 3: A1 and A2 Only Enabled
Setting 4: A3 Only Enabled
