EM303A General Purpose Inverter

Two terminal control modes: 2-wire sequence and 3-wire sequence
2-wire sequence:
F0-05=0
ON/OFF of terminal RUN controls start/stop of inverter, and OFF/ON of
terminal F/R controls forward/reverse. If F0-24=1, when 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 ON/OFF of terminal RUN controls forward/stop of inverter, and ON/OFF
of terminal F/R controls reverse/stop. If terminals F/R and RUN are ON
simultaneously, the inverter stops according to the setting mode. When 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 (d).

When F0-05 start/stop is selected as 0 or 1, even if terminal RUN is ON, and
monocyclic time of PLC is up, pressing STOP button or external stop
command of terminal can stop inverter. Meanwhile, inverter reenters running
status only after terminal RUN is required to be OFF once and then ON again.
