3.4 、TO CNC
Connection and pin definition see Fig 3-4 shows:
Fig 3-4 XPTHC-4 TO CNC connection
Note：
A、 ALL to CNC controller’s signals use optical isolation, original set is low-level
effective.
B、 Arc OK signal（arc feedback 1、arc feedback 2）is a switch signal.
C、 Arc feedback signal adopts the 200mA NPN OC door output, it could connect to the
input of the CNC’s arc enable directly, also could connect to the 24V/100mA Relay.
TO CNC pin definition as follow:
Pin(s) Signal Description & Ratings
1 EXAUTO
Auto Signal，Control level depends on P7
parameter setting,
Controlled by CNC’s corner signal or THC
enable signal, Pin8 is control Com
2 UP
Up signal, low-level effective
Pin8 is control Com
3 DOWN
Down signal, low-level effective
Pin8 is control Com
4
ARC ON with IHS
(IHS_ARCON)
Arc start with IHS, low-level effective
Pin8 is control Com
5
EX ARC ON Arc start without IHS, low-level effective
Pin8 is control Com
6
ARC Feedback
Arc feedback output，connect to CNC’s Arc
enable input, via P2 parameter relay output
Optical Isolation NPN OC door output，
Max:200mA
7
COLLISION output
Optical Isolation NPN OC door output，
Max:200mA
8 Control COM Isolation Control COM
