n H3-09: Terminal A2 Signal Level Selection
Selects the input signal level for analog input A2. Be sure to also set DIP switch S1 on the terminal board accordingly for a
voltage input or current input.
No.
H3-09
Setting 0: 0 to 10 Vdc with Lower Limit
The input level is 0 to 10 Vdc. Negative input values will be limited to 0. Refer to the explanation of H3-01, Setting 0.
to Setting 0: 0 to 10 Vdc with Limit on page 204
Setting 1: 0 to 10 Vdc without Lower Limit
The input level is 0 to 10 Vdc. Negative input values will be accepted. Refer to the explanation of H3-01, Setting 1.
Setting 1: 0 to 10 Vdc without Limit on page 205
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 (like setting 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 (like setting 0).
n H3-10: Terminal A2 Function Selection
Determines the function assigned to analog input terminal A2.
page 208 for a list of functions and descriptions.
No.
H3-10
n 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.
No.
H3-11

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 both analog inputs A1 and A2.
No.
H3-13
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.
