2.3.5 Assigning signals (output stop signal (MRS), reset signal (RES), etc.) to contact
input terminals
POINT
y Use parameters (Pr.178 to Pr.182 input terminal function selection) to select and change the functions assigned to
input terminals.
To assign the output stop signal (MRS) to the terminal RH, for example, assign "24" to Pr.182 RH terminal
function selection. Refer to page 4 to change the parameter setting.
y Set Pr.160 Extended function display selection = "0" (extended parameters enabled).
