n H3-05: Terminal A3 Signal Level Selection
Determines the function assigned to analog input terminal A3.
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 Vdc on page 201.
Setting 1: –10 V to 10 Vdc
The input level is -10 to 10 Vdc. See the explanation provided for H3-01. Refer to Setting 1: –10 to 10 Vdc on page 201.
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 204 for a list of functions and descriptions.
When analog input A3 is used as PTC input set H3-06 = E and make sure switch S4 on the terminal board is set for PTC
input. Also refer to Terminal A3 Analog/PTC Input Selection on page 67.
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).
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.
Setting 0: 0 to 10 Vdc
The input level is 0 to 10 Vdc. Refer to Setting 0: 0 to 10 Vdc on page 201
Setting 1: –10 to 10 Vdc
The input level is –10 to 10 Vdc. Refer to Setting 1: –10 to 10 Vdc on page 201.
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%.
