2) Analog input
Refer to chapter 6 for detail of analog input characteristic setting.
Example of set value setting
Input the set value to terminal [RX] by 0 to 10V.
Input the feedback signal of 1 to 2 atm into terminal [II] by 4 to 20mA signal. Convert the input level 4-20mA
by terminal [II] to 0-60Hz.
