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.
Purpose Parameter that should be Set Refer to Page
