Sin as the enabling terminal, and the
running command is generated by FWD,
while the direction is controlled by REV.
During running, the Sin terminal needs to
be closed, and terminal FWD generates a
rising edge signal, then the VFD starts to
run in the direction set by the state of
terminal REV; the VFD needs to be stopped
by disconnecting terminal Sin.
