H3-07, H3-08: Terminal A3 Gain and Bias Setting
Parameter H3-07 sets the level of the selected input value that is equal to 10 Vdc input at terminal A3 (gain).
Parameter H3-08 sets the level of the selected input value that is equal to 0 V input at terminal A3 (bias).
No.

H3-09: Terminal A2 Signal Level Selection
Selects the input signal level for analog input A2. Set Jumper S1 on the terminal board accordingly for a voltage input or
current input.
No.
H3-09
Setting 0: 0 to 10 V with Zero Limit
The input level is 0 to 10 Vdc. Negative input values will be limited to 0.

98.
Setting 1: 0 to 10 V without Zero Limit
The input level is 0 to 10 Vdc. Negative input values will be accepted.
page
98.
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%.
n
H3-10: Terminal A2 Function Selection
Determines the function assigned to analog input terminal A2.

for a list of functions and descriptions.
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.
n
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.
H3-11
H3-12
n
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.
