 Torch lifter after cutting
After finishing the cutting, THC will control torch to go up, up height is set by P8
parameter.
 Arc voltage enable output(piercing completed output)
It delays the signal via setting the P2 parameter on operation panel. This signal is test by
arc voltage signal. The arc enable signal is using 200mA optical coupler OC door output, it
could connect to the CNC’s ARC enable directly.
 Anti-collision function
When THC stops work, it’ll send the collision signal within 0.2 second if any material
touches the torch and actives the proximity switch.
During auto work, except for IHS, it’ll send the collision signal within 0.2 second if any
material touches the torch and actives the micro switch or proximity switch. The collision
signal is using 200mA optical coupler OC door output, it could connect to the CNC’s collision
input directly.
 Offering E1 to E5 warnings
E1：Communication error
E2：Corner signal logic setting error
E3：ARC detect failure
E4：Over-voltage protection (actual arc voltage - setting arc voltage> 30V ), it works at the
setting arc volt mode, doesn’t work at the sample arc volt mode.
E5：Collision warning
