If the auto speed is set as 0, the system will have this problem.
8. Why the motor does not work or is similar to death when it is in “Manual” state?
Answer: Please check the “Manual speed limit” to see whether it is a proper speed, and check whether
percentage of manual processing is too low.
If the manual speed is set as 0, the system will have this problem.
9. The processing code has the “Return” instructions. However, why the device does not return to the
home position after having finished the track?
Answer: Please check the “Manual speed limit” to see whether it is a proper speed, and check whether
percentage of manual processing is too low.
10. Why the right angle of the cutting square is not vertical?
Answer: Debug the start-up speed and the acceleration of “Speed” in “Parameter” again.
11. Why the anti-interference performance of plasma is poor?
Answer: Check whether all ground wires are connected well, or whether the external power filter is
isolating the high frequency.
12. Why, one of the solenoid valves cannot work?
Answer: You can judge whether it is caused by the system damage or relay/solenoid valves damage in the
following ways.
1) Change for a new solenoid valve of the same type to judge whether it is broken, or press [Ignition] in
the “Auto” interface, and press [Preheat Oxygen], [Acetylene] and [Cutting Oxygen] to output a
signal manually, then, use a multimeter to test the input end of the solenoid valve to see whether there
is voltage signal.
2) If there is no voltage signal in the input end of the solenoid valve, then, open the case and use the
same method as above to test the input end of the relay to see whether there is voltage signal, and to
judge whether it is damaged or not.
3) If the relay has no voltage signal, that may be the damage of output end of NCS. Change for the
backup output according to the following steps.
4) Open the case and the output port as the following picture:
