Setting 1: 0 to 10 Vdc Bipolar
The input level is -10 to 10 Vdc. If the resulting voltage is negative after being adjusted by gain and bias settings, then the
motor will rotate in reverse.

H3-03, H3-04: Terminal A1 Gain and Bias Settings
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 (bias).
Use both parameters to adjust the characteristics of the analog input signal to terminal A1.

Setting Examples
• Gain H3-03 = 200%, bias H3-04 = 0, terminal A1 as frequency reference input (H3-02 = 0):
A 10 Vdc input is equivalent to a 200% frequency reference and 5 Vdc is equivalent to a 100% frequency reference. Since
the drive output is limited by the maximum frequency parameter (E1-04), the frequency reference will be equal to E1-04
above 5 Vdc.

Figure 5.63 Frequency Reference Setting by Analog Input with Increased Gain
• 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.
