specifications can be
changed by analog input
specifications switchover
(Pr. 73) (initial settings in
frame). Terminal 10 and
terminal 2 are used as PTC
input terminal (Pr. 561).
*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 to 10 V) and "I" to select
current input (0/4 to 20 mA.)
To use terminal 4 (initial setting is current input), set "4" in
any of Pr.178 to Pr.182 to assign the function.
