Frequency setting by analog input (terminal 2, 4)

4.16 Frequency setting by analog input (terminal 2, 4)

4.16.1 Analog input selection (Pr. 73, Pr. 267)

(1) Selection of analog input specifications

For the terminal 2 for analog voltage input, 0 to 5V (initial value) or 0 to 10V can be selected.

Either voltage input (0 to 5V, 0 to 10V) or current input (4 to 20mA initial value) can be selected for terminal 4 used for
analog input.
Change the input specifications to change Pr. 267 and voltage/current input switch.
