ACI2 Minimum frequency (percentage of Pr.1-00)

Factory Setting: 0.00

04 - 20

ACI2 Maximum frequency (percentage of Pr.1-00)

Factory Setting: 100.00

Settings 0.00~100.00% Unit: 0.01

 The above parameters are used to set the analog input reference values. The min and max

frequencies are based on Pr.01-00 (during open-loop control) or the PID reference value Pr.10-01

(during PID close-loop control).

Please refer to the following diagram for more details:

 Example: Using the AVI (0~10V) as the target source and ACI1 (4~20mA corresponds to 0~5Pa)

and ACI2 (0~10mA corresponds to 0~4Pa) as the feedback location for a pressure sensor connected.

If your target value is between 3~7Pa (Set Pr.10-01 to 10, other parameters settings refer Pr.10-01 to

set as shown in the following diagram and then setting the PID feedback relative parameters.) If

setting AVI to 7.5V, pressure sum of ACI1 and ACI2 could be controlled at 6Pa.
