When you say the spindle amp would not boot, was it dead, with no display? Does the spindle load bar graph on the screen show a high load when rotating the spindle? After replacing the amp, the...

The dipswitch may be for draining the memory support supercapacitor (useful for resetting the CMOS when things get glitched). When you switched the dipswitch to "on", you may have caused a...
Not at all sure of this, but with the Fanuc controls, it needs the M06 first. And possibly use the tool number in 2-digit form, with a leading zero if necessary, and possibly add a second 2-digit...
Also, you said the Field Ready LED extinguishes. Is that saying that the field supply stopped sending current to the field due to the Tach Loss, or due to a failure of the supply itself? What model...
Yeh the Tach Loss generally means the drive tried to send current to the motor but not seeing any tach voltage in response. This often is due to failure in the drive itself, as you are now seeing. ...
Martin, Have you been able to repair the problem yet? I had a similar problem a few years ago, and I am going to look for my records on it. Al I remember so far is that there was a board behind the...
I doubt that you damaged the encoder by not switching the connections correctly on the axes. It's more likely that when the motors "struggled", the encoder coupling may have been damaged. The...
I found in search on Yahoo that a 8055M is a Fagor machine, is that correct? Do you know if the monitor is CGA or VGA? If CGA, I recently found a nice converter (Moncotech's MVC007) to convert that...
My experience with that kind of sudden-onset vibration is that the coupler from the encoder to the motor or the ball screw is loose or broken, or else that the encoder has a bad spot, so check the...
If you are stopping the buzz when you touch either side of the power supply capacitor, it sounds like you are grounding the circuit with your finger. Try putting a small wire from the negative (-)...

Yo estoy aprendiendo el español poco a poco.. Gracias si usted me perdonaría los errors aqui. Si usted quiere, por favor corríjame por esos errors.
Yo tengo un torno Nardini...
Chris,
I noticed that you have a Nardini with a Fanuc 20T CNC. I am desperately in need of a set of electrical prints and ladder diagram for a Nardini lathe with a 21T (supposedly compatible),...
I've been repairing the electronics and electrical problems on CNC and NC machines for about 15 years, and commercial / industrial 2-way radios for the 15 years before that. Last year, my employer...
What kinds of widgits do you master / make?
Don
Not to be too picky, but I always saw it spelled "widget" (I just started using the Yahoo! Widget engine, lots of cool ways to junk up your desktop and gum up your computer's operations!).
Please...
Anyone going to do more on this? There are still things I need to learn, after repairing industrial electronics / electrical for the last 15 years.
Right now I'm looking for the def for "Gantry"...
