Still having repeated problems with the spindle drive on the lagunmatic 3516 w/yaskawa 626vm3
Here is the timeline of repairs
Rebuilt spindle moter 7/2012
Replaced encoder 8/2012
Rebuilt drive in 10/2012
Ran untill 12 2012
swaped a couple of boards power supplies then installed a buck booste transformer to get the voltage right on spec.
Ran for about two weeks.
The repair guys swaped me for a complete different drive.
Went down on day 30.
Rewired the machine and added a noise filter directly to the drive in case there was interference coming from something in the machine.
Ran it all last week 10-15 hours a day.
turned on today and drilled 12 holes went and had lunch and it is alarming out again.
When this fails it always fails when sitting. Usually when I am doing a setup or programming. It has never failed after running all day long.
It always seems that it will start up and run again a few days later. I will prove that out this time.
I believe this is an external cause but without a consistent problem how do you diagnose it?
