5.7 H: Terminal Functions
• Gain H3-03 = 100%, bias H3-04 = -25%, terminal A1 as speed reference input:
An input of 0 Vdc will be equivalent to a -25% speed reference.
When parameter H3-01 = 0, the speed 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.

H3-09: Terminal A2 Signal Level Selection
Selects the input signal level for analog input A2.
No.
H3-09
Setting 0: 0 to 10 Vdc
The input level is 0 to 10 Vdc. Refer to
Setting 1: –10 to 10 Vdc
The input level is –10 to 10 Vdc. Refer to
■
H3-10: Terminal A2 Function Selection
Determines the function assigned to analog input terminal A2. Refer to
on page 199 for a list of functions and descriptions.

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 to terminal A2.
Parameter H3-12 sets the level of the input value selected that is equal to 0 V at terminal A2.
Both can be used to adjust the characteristics of the analog input signal to terminal A2. The settings work in the same way
as parameters H3-03 and H3-04 for analog input A1.
