*5 Terminal input specifications can be changed by analog input
specifications switchover (Pr. 267) (initial settings in frame). Set
the voltage/current input switch in the "V" position to select
voltage input (0 to 5 V/0 to10 V) and "I" (initial value) to select
current input (4 to 20 mA). To use terminal 4 (initial setting is
current input), set "4" in any of Pr. 178 to Pr. 184 (input terminal
function selection)to assign the function, and turn ON AU
signal.

tions can be changed by
