When the "3-wire input mode" is set with the "Operation input mode selection" parameter, the following signals are applied.
FWD_R

START/STOP_R, REV_R
→
RUN/BRAKE_R, STOP-MODE_R
→
FWD/REV_R
Output signals shown below can be assigned to the output terminals NET-OUT0 to NET-OUT15 of the remote I/O
by setting parameters.
Refer to "Parameter R/W commands [I/O function (Remote I/O)]" on p.30 for details on parameters.
