Fig. 7-1 Two-line Control
When the start/stop value of F00.03 is set to 0 or 1, even if the terminal RUN
is available, the inverter can be stopped by pressing the STOP key or sending
an external stop command to the terminal. In this case, the inverter will not
be in the running status until the terminal RUN is disabled and then enabled.
Three-line control:
F00.03=2: the terminal RUN controls forward running, the terminal Xi is for stop,
and the terminal F/R is in the reverse status.
The terminal RUN is normally ON for forward running, and the terminal F/R is
normally ON for reverse running, with valid pulse edges. The terminal Xi is normally
closed for stop, with the valid level. When the inverter is in the running status, press Xi to
stop it. When the mode of deceleration to stop (F04.19=0) is selected, the logic diagram is
as shown in Fig. 7-2(b). The terminal Xi is for “three-line running and stop control” as
defined by F02.00 to F02.04.
F00.03=3: the terminal RUN is for running, Xi for stop and F/R for
forward/reverse control.
The terminal RUN is normally ON for running, with the valid pulse edge, F/R for
forward/reverse switching (forward in the OFF status and reverse in the ON status), and Xi
is normally OFF for stop, with the valid level. When the mode of deceleration to stop
(F04.19=0) is selected, the logic diagram is as shown in Fig. 7-2(d).
