3 FootSW Input port of foot switch. The connection method is:
when the pedal is stepped down, the low-level signal
will be inputted to this port; when the pedal is
released, the port will be disconnected or the
high-level signal can be inputted to this port; when
the stepped-down pedal is held for not less than 100
ms, if the machine lies idle, it can be started for work;
if the machine is in the working state, the work will
be suspended; of the machine is in the suspension, the
work will be restarted, that is to say, the function of
the pedal switch is the same as that of the
“Start/Pause” key. If the interval time to the first
stepping-down of the pedal should be less than 1.5
seconds when the pedal is stepped down once again,
the second stepping-down of the pedal will be
considered invalid by the controller.
