Setting 0: 0 to 10 Vdc with Limit
The input level is 0 to 10 Vdc. Negative input values will be limited to 0.
Example: Terminal A1 is set to supply the frequency reference, and the bias (H3-04) is set to -100%. The frequency
reference can be set from 0 to 100% with an analog input of 5 to 10 V. The frequency reference will be zero when the
analog input is between 0 and 5 V.

Setting 1: 0 to 10 Vdc without Limit
The input level is 0 to 10 Vdc. Negative input values will be accepted.
Example: Terminal A1 is set to supply the frequency reference, and the bias (H3-04) is set to -100%. The frequency
reference can be set from 0 to 100% with an analog input of 5 to 10 V. With an input of 0 to 5 V, the frequency reference
can be set from -100% to 0%. The drive reverses the motor rotation with negative input.

H3-03/H3-04: Terminal A1 Gain/Bias Setting
Parameter H3-03 sets the level of the selected input value that is equal to 10 Vdc input at terminal A1 (Gain).
Parameter H3-04 sets the level of the selected input value that is equal to 0 V input at terminal A1.
Both can be used to adjust the analog input A1 characteristics.
