H3-09: Terminal A2 Signal Level Selection
Selects the input signal level for analog input A2. Set DIP Switch S1-2 on the terminal board accordingly for a voltage input
or current input.
No. Name Setting Range Default
H3-09 Terminal A2 Signal Level Selection 0 to 3 2
Setting 0: 0 to 10 Vdc
The input level is 0 to 10 Vdc.
Refer to Setting 0: 0 to 10 Vdc on page 182.
Setting 1: 0 to 10 Vdc Bipolar
The input level is -10 to 10 Vdc. Refer to Setting 1: 0 to 10 Vdc Bipolar on page 183.
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.
No. Name Setting Range Default
H3-10 Terminal A2 Function Selection 0 to 32 B

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. Name Setting Range Default
H3-11 Terminal A2 Gain Setting -999.9 to 999.9% 100.0%
H3-12 Terminal A2 Bias Setting -999.9 to 999.9% 0.0%
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. Name Setting Range Default
H3-13 Analog Input Filter Time Constant 0.00 to 2.00 s 0.03 s
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 for A1 and A2 (H3-02 and H3-10)
This section describes the various functions that can be assigned to terminals A1 and A2 by setting H3-02 and H3-10.
Note: 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.
