• 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.
When parameter H3-01 = 1, the motor will rotate in reverse between -10 and 2 Vdc input.

n 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 149 .
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 149 .
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%.
n 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
n 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.
