Note: For the 2-wire running mode, when FWD/REV
terminal is valid, the VFD stop because of the stopping
command from other sources, even the control terminal
FWD/REV keeps valid; the VFD won't work when the
stopping command is canceled. Only when FWD/REV is
relaunched, the VFD can start again. For example, the
valid STOP/RST stop when PLC signal cycles stop,
fixed-length stop and terminal control (see P07.04).
