the protective signal can be inputted from this pin. This pin can
be enabled and prohibited. This signal is not inquired by the
mainboard if this pin is prohibited; if this pin is enabled, when
the input is high-leveled or this input port is suspended, the
machine will be protected, the work suspended and the laser
closed.

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 mainboard.

The spacing polarity is optional, that is to say, when the motion axle reaches the
spacing position, it will trigger a low-level signal so as to make the corresponding LED
(under the cover) light; when the motion axle leaves the spacing position, it will trigger a
high-level signal or disconnect the spacing signal so as to make the spacing indicator go
out, but when it leaves the spacing, the corresponding indicator will light and the spacing
polarity become positive. The mistaken setting of spacing polarity will result that the
spacing can’t be detected when the system is reset so as to lead to the collision of axles.
