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.

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

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
