4.9 3-axle Spacing and Special Input Interface CN3/CN4
Z-axle spacing and special input interface CN3 (6Pin, 3.81mm space)
Special input 2, protective port. If the machine needs
to be protected in the special state (such as cover open
protection), the protective signal can be inputted from
this pin. This pin can be enabled and prohibited. This
signal is not inquired by the controller 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.
Special input 1, 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.
