2: Three-wire control, integrate Enable with direction. At this mode, SIn is the Enable
terminal with the direction controlled by the defined FWD and REV. But pulse is valid, and the
STOP is achieved by disabling SIn terminal signal.

SIn is defining the corresponding terminal function as Function 3 “Three-wire operation
control”.
3: Three-wire control, separate Enable from direction. At this mode SIn is the Enable
terminal, and FWD is the on-off control terminal
establishing two-stage Enable with direction
determined by REV status. Pulse is valid. The diagram is shown in Figure 6-11.
Note: For two-wire operation mode, when FWD/REV terminal is enabled and the stop
command produced by other sources stops the equipment, the inverter does not start
to operate after the stop command disappears even if the control terminal FWD/REV is
still valid. If the inverter needs to operate, it is required to trigger FWD/REV again. For
instance, PLC single loop stop, fixed length stop, valid STOP/RST stop under terminal
operation command channel (P7.04).
