Maintenance Tips

 

 Intermittent problem

 This is one of the most difficult problems to work with. If a problem appears and disappears intermittently, you have to corner it down to one of the causes, and try to simulate the condition. By trying to simulate the condition and making it fail is the starting point.

 Find out whether this happens at a certain time or operation. Certain time could mean temperature related. Certain operation means it is loose connection.

a)      Temperature related  - Next thing is to find out whether it is cold related or heat related. If it happens when it gets hot try to put a fan or keep the cabinet open and see if it helps. Another way is to use a light heat gun and try to heat that particular area and see whether the same failure happens. This is the only way to troubleshoot a temperature-related problem. This kind of problem is more in non air-conditioned shop floor and in summer. Cold related problems are exactly opposite and the ratio of happening is 10 to 1.

 b)      Vibration related happens at a particular movement when some wire might get pinched. Attention has to be paid to find exactly when it happens. Then try and move those wires and see whether you could get it to recreate.

c)      Coolant related - Due to coolant coming on a motor or cable make this error happen at that time by shorting a wire to the ground.

Maintenance Quiz - Check your knowledge on machines
 
  Actual case - The machine 24V was shorting out while running only.   It is a 10 Amp breaker. There is no short on 24V. How do you go about troubleshooting this type of shorting out problem.  Answer in the next issue

Last Issue :  My Fanuc drive runs rough in one direction. Motor does it without mechanics connected to it. Motor and feedback pulse coder checked out ok. Drive has a 16 week lead time. Drive repair people checked the drive and say drive components all look good. They also say all the control components are the same driving and it cannot be the drive. Should I spend $40,000 and buy a drive?

Answer - In Fanuc drives there are two current transformers used to sense the current feedback. Each one is used for a different direction. When they go bad one direction will be better and other can be bad. It is the drive.
