Ans:
During machining , The screen change to black then machine is stopped then Screen shown above alarm , Hereby we would like to inform you that the above 1,2, 6 alarm is the same group alarm , The control unit loss data , So ask machine emergency stop , While you turn on power again, The control unit just remind you the machine happen the above problem , You need to solve the problem before start machining , After you solve the problem , Then turn off power and turn on power again , the alarm will go away if the problem was solved.
Now we would like to inform you that there are two possible reasons caused the problem
- Maybe your Power source R,S,T (400V) happen short circuit short time , For example R,T loss voltage or S, T loss voltage etc.. then control unit (screen) loss 220V power then screen change to black , Besides please check the control unit 220V power wire at top wire block , The two wire is NO.2 and No. 11 , Please check the wire was tighten well no loss problem . On the other hand please check the power ON button light color , While happen the problem if power on lamp change to red color , It mean the problem caused by your main power source happen short circuit problem.
- While happen the above problem , if the power On lamp color still under green color , It mean your main power source OK. no problem , Then it is possible caused by control unit problem . We need you to take a video for our engineer reference then we just can check and help you to find the real reason and solve the problem asap.
