I have some servo driver boards that intermittantly fail and would like some information on getting them repaired. Do any of the members know of a 3rd party repair facility that can repair/exchange these boards? As not having a schematic for these so

Hi everyone, We bought a used Juki KE a few months ago. Installed it at the beginning of this year, but have some problems with the Z and ROT servos. As soon as the machine is powered on, the ALM04 red led turns on on some of the Z and ROT drivers.

are you sure #1 and #6 are interchangeable? if I remember correctly there is a catch with those motors, like there are 2 groups, group 1 being #1 #3 #5 and group 2 being #2 #4 and #6. maybe try getting it back and swapping cables at drivers for head

I will try outline Theta and Z-axis servo issues, we were facing last time. Story behind. Our 750 is used seldom and last time after switching it on initialization procedure ends with T axis of right head: Servo alarm. Opening front cover of 750 two

Fuji is usually the cheapest you will find. I think around $750 for them to repair it. the last time I checked they have an exclusive patent on their PCB backplane design so there would not be any real way to bench test it. they also have rights to t

If there are no errors, check main relay contacts, it is common that one contact is not closing.

Problem solved. Thru the help of MyData support we have determined that older MyDatas have a software issue with the servo drivers. A newer rev of driver will fix this problem.

The so-called "drivers" are used to control each servo - control boards at the back of the machine. There are several (8?). If one is "worn out" and has no strength to move the servo, maybe this is where the error comes from? They can be interchanged
