: Our industrial unit, a large-scale packaging facility, has been experiencing a consistent issue with the conveyor system. The belt constantly breaks down, causing significant delays in product packaging and resulting in lost revenue. This leads to increased labor costs as we're forced to manually sort packages. The current estimated repair cost is high, likely exceeding $50,000, given the complexity of the machinery involved. Given this ongoing problem, Im concerned about a long-term solution to prevent these frequent breakdowns and maintain our production capacity.:

I have a Mitsubishi lathe model M-TC8A serial TC8A-005. I believe one of the soft keys on the controll is sticking. I have removed both the small board and large board and cannot find anything wrong with them. I am pretty sure that one is sticking because I can here the beep and all my lights flash on and off on the controll. Is there a way to test these boards? Operator Board unit MH402A-1 serial 8911007. I am not sure whick numbers on the boards are part numbers.Thanks,Tim Van Bruggen, ownerCAM Specialties, LLC

#Mitsubishi by jay on 2011-08-30 15:28
the error you have is a F6 3b and it means that the unit has over heated, you can power down for 20 min and it may clear its self if not you may need a new drive als make sure the cooling fan on the side is running

Based on my previous experience, the MITSUBISHI PD21B CNC module might be experiencing intermittent power loss resulting in frequent system freezing during operation. This could indicate a potential issue with the power supply or internal connections. Further inspection by a qualified technician is recommended to identify and address the root cause of the problem.
