7. The motor doesn’t work or is similar to crash in auto mode
A: Please check whether “Auto speed limit” is set to appropriate speed and whether the manual processing
percentage is too low.
This will occur if the manual speed is set to 0.
8. The motor doesn’t work or is similar to crash in manual mode
A: Please check whether “Manual speed limit” is set to appropriate speed and whether the manual percentage is
too low.
This will occur if the manual speed is set to 0.
9. The processing code has returning reference instruction, but doesn’t return after running
A: Please check whether “Manual speed limit” is set to appropriate speed and whether the manual percentage is
too low.
10. The right angle of the cut square isn’t vertical
A: Re-adjust the start speed and acceleration in “Speed” of “Parameters”.
11. Plasma is poor in anti-interference
A: Check whether the grounding is proper or isolate the high frequency of external power supply filter.
12. Certain electromagnetic valve doesn’t work
A: Check whether the problem is caused by system damage, relay or electromagnetic valve damage in the
methods below.
1) Replace with an electromagnetic valve of same specifications to check whether the electromagnetic
valve is damaged, or press [Ignition][Preheating oxygen][Ethyne][Cutting oxygen] in the automatic
processing interface to output a signal manually, and then check whether the input end of the
electromagnetic valve has voltage signal with a multimeter.
2) If the input end of the electromagnetic valve doesn’t have voltage signal, open the case and check
whether the input end of the relay has voltage signal in the same method to check whether the relay is
intact.
