selection
*. Select with the Input conversion
switch on the side of the module
(on: current, off: voltage)
*. When current input is used, set the
Input range switch to V1 / I. *. Select in accordance with the
Input terminals.
*. Connect the V terminal with the
I terminal on the use of
current input.
*. Select with the Input conversion
switch on the side of the module
(on: current, off: voltage)
*. Select with program initial F/B
(input variable:IN_SEL, 0:current,
1:voltage)
