n H3-05: Terminal A3 Signal Level Selection
Selects the input signal level for analog input A3. Refer to Multi-Function Analog Input Terminal Settings on page 178 for
a list of functions and descriptions.
No. Name Setting Range Default
H3-05 Terminal A3 Signal Level Selection 0 to 3 0
Setting 0: 0 to 10 Vdc
The input level is 0 to 10 Vdc. See the explanation provided for H3-01. Refer to Setting 0: 0 to 10 V with Zero Limit on page
175 .
Setting 1: -10 to 10 Vdc
The input level is -10 to 10 Vdc. See the explanation provided for H3-01. Refer to Setting 1: 0 to 10 V without Zero Limit
on page 175 .
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 H3-06: Terminal A3 Function Selection
Determines the function assigned to analog input terminal A3. Refer to Multi-Function Analog Input Terminal Settings on
page 178 for a list of functions and descriptions.
No. Name Setting Range Default
H3-06 Terminal A3 Function Selection 0 to 26 2
n 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. Name Setting Range Default
H3-07 Terminal A3 Gain Setting -999.9 to 999.9% 100.0%
H3-08 Terminal A3 Bias Setting -999.9 to 999.9% 0.0%
n 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. Name Setting Range Default
