AUI Input Gain

a Factory Setting: 100

Settings 01 to 200% Unit: 1%

No AUI Negative bias command

Factory Setting: 00

Settings 00 No ACI Negative bias command

01 Negative bias, REV motion enabled

02 Negative bias, REV motion disabled

 Pr.04-00 ~ 04-03, Pr.04-11 ~ 04-18 are used when the source of frequency command is

the analog signal. Refer to the following examples.

Example 1:

10V

20m

Factory Settings

Pr.01-00=60Hz--Max. output Freq.

Pr.04-11=0%--bias adjustment

Pr.04-12 =0-- bias polarity

Pr.04-13=100% -- pot. freq. gain

Pr.04-14=0 -- REV disable in negative bias

30Hz

Example 2:

In this example with the potentiometer set to 0V the Output Frequency is 10 Hz. The mid-point

of the potentiometer becomes 40 Hz. Once the Maximum Output Frequency is reached any

further increase of the potentiometer will not increase output frequency. (If you want to use the

range of 60Hz, please refer to the example 3.) The value of external input voltage/current

0-8.33V (4-13.33mA) corresponds to the setting frequency 0-60Hz.
