Servo motor stops working

[queenslander]

Hi folks and good morning from Australia 

I have a slight problem with my Cowboy CB4500 and servo motor

The machine is 10yr old but has done very little work and most of that is 8/9oz.Today I have gone to sew and switch the power on everything lights up as per normal the LED on the front has these little [ ] things that just revolve around the screen as per normal no noise at all, have pulled all power connections (plugs) out put them back in switched power off for a while switched it back on again I am at a loss as I only used it a month ago and it was perfect.

The only thing I have put it down to is we did loose power for about 2 days due to flooding in the north of the country and I did hook up a generator for that time and the machine was plugged in to the wall maybe a power spike from the generator, but then it should not switch the LED screen on.I DON’T KNOW

Have you checked the fuse on the servo motor???

Hi keg 

Thank you for your reply and did check the fuse all ok.I then started to have a good look around  and found the speed sensor lever on the side of the servo motor was loose so undid the 4 screws and took the panel with the lever attached and then found the problem 

The black plastic blade that moves in the u section of the optical sensor was just layered in the housing so put it back on the shaft played for a little while to get it in the right position and off she went problem solved 

It appears that it has never been tightened from factory 

Cheers to all and thanks

Good to hear you found it. We would have been guessing for any good answers on that one.
