4.15.1 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.
Rated specifications of terminal 4 change according to the voltage/current input switch setting.
Voltage input: Input resistance 10k1k, maximum permissible input voltage 20VDC
Current input: Input resistance 2335, maximum permissible input voltage 30mA
