• Gain H3-03 = 100%, bias H3-04 = -25%, terminal A1 as frequency reference input:
An input of 0 Vdc will be equivalent to a -25% frequency reference.
When parameter H3-01 = 0, the frequency reference is 0% between 0 and 2 Vdc input.

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 92.
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 92.
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%.
