n H3-01: Terminal A1 Signal Level Selection
Selects the input signal level for analog input A1. Set jumper S1 on the terminal board accordingly for voltage input or current
input.
No. Name Setting Range Default
H3-01 Terminal A1 Signal Level Selection 0 to 3 0
Setting 0: 0 to 10 V with Zero Limit
The input level is 0 to 10 Vdc with zero limit. The minimum input level is limited to 0%, so that a negative input signal due
to gain and bias settings will be read as 0%.
Setting 1: 0 to 10 V without Zero Limit
The input level is 0 to 10 Vdc without zero limit. If the resulting voltage is negative after being adjusted by gain and bias
settings, then the motor will rotate in reverse.
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 are 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 are limited to 0%.
n H3-02: Terminal A1 Function Selection
Selects the input signal level for analog input A1.
No. Name Setting Range Default
H3-02 Terminal A1 Function Selection 0 to 41 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
H3-09 Terminal A2 Signal Level Selection 0 to 3 2
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. Refer to Setting 0: 0 to 10 V with Zero Limit on
page 169 .
Setting 1: 0 to 10 V without Zero Limit
The input level is 0 to 10 Vdc. Negative input values will be accepted. Refer to Setting 1: 0 to 10 V without Zero Limit on
page 169 .
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.
