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
100ms when the pedal is stepped down once again, the
second stepping-down of the pedal will be considered invalid
by the controller.
Input from protective port. If the machine needs to be
protected in the special state (such as door 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.
Input for manual laser on/off. Low level is to open laser and
high level or no-connection is to close laser.
General Input, with the function reserved.
24V Power positive output (If the interface of main power
source is powered with 24V power supply, this pin should be
24V; if it is powered with 36 V power supply, this pin should
be 36V.)

The limit from axis Y+ and Y to max. coordinate

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