Collision output to CNC
HF100 has Anti-collision function,it is effective on both manual/auto mode.
When steel or other conductive item touches sensor ring, torch lift up, and the
collision signal is sent out from the Pin3 of 7-pin socket(OC door), when CNC
receives this signal, machine pauses and waits for treatment of collision. When
collision happens, the LED indicator(collision) on operation panel turns on.
Normally human
’
s hand touches sensor ring, indicator would turn on and
send out collision signal. If user changes HF cable, or HF cable spec changes,
indicator might turn on, like follow situation, HF cable short-circuit, once it
happens, indicator turns on, torch lift up. It could be confirmed by checking the
HF cable shield net and Signal connect or not. HF cable gets longer, it needs
to adjust to find the Balance point, then THC can work right on Auto mode, and
indicator will turn off.
