：
F0-05=0
Start/stop of inverter is under control of ON/OFF of terminal RUN, and
forward/reverse of inverter is under control of OFF/ON of terminal F/R. If F0-24=1 and
reverse is prohibited, terminal F/R is off. When stop mode is selected as ramp-to-stop, the
sequence diagram is as shown in Figure 7-2 (b).
F0-05=1
Forward/stop of inverter is under control of ON/OFF of terminal RUN, and
