Frequency setting

I set the frequency by inputting the current signal 4 to 20 mA from an external source to the terminal 4, but the initial setting does not go well with this.
I want to have 60 Hz for the current signal 4 mA and 0 Hz for 20 mA.

Answer

The parameters used when the terminal 4 is used are C5, C6, 126, and C7.
Set Pr.C5 (Terminal 4 frequency setting bias frequency) while feeding a current signal of 4 mA.
Change the frequency to 60 Hz for this time.
Also, set Pr.C6 (Terminal 4 frequency setting bias) in this state. (Reading Pr.C6 shows a value close to 20.)
Then, set Pr.126 (Terminal 4 frequency setting gain frequency) while feeding a current signal of 20 mA.
Change the frequency to 0 Hz for this time.
Also, set Pr.C7 (Terminal 4 frequency setting gain) in this state. (Reading Pr.C7 shows a value very close to 100.)
