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.
