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 mainboard.

DrProc
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
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.

Shot
Input for manual laser on/off. Low level is to open laser
and high level or no-connection is to close laser.
5
IN1
General Input, with the function reserved.
6
+24V
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.)

Pin Symbols
Definitions
1
GND
Power ground (output)
2
LmtY-
The spacing from axle Y- and Y to 0 coordinate
3
LmtY+
The spacing from axle Y+ and Y to max. coordinate
4
LmtX-
The spacing from axle X- and X to 0 coordinate
5
LmtX+
The spacing from axle X+ and X to max. coordinate

5V Power positive (output)
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.
The pin definitions of Z/U axle spacing input CN3 are the same as CN4.
