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.

4

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.)

Definitions

Power ground (output)

The spacing from axle Y- and Y to 0 coordinate

The spacing from axle Y+ and Y to max. coordinate

The spacing from axle X- and X to 0 coordinate

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.

All XYZU axle spacing inputs are compatible to 5V/12V/24V logic level inputs。
