If exchanging encoders this should be possible just by making suitable
alignment marks when disassembling.

(I have swapped an encoder for a resolver on a motor and it still
worked afterwards)

Useing a halmeter, take a look at motion.adaptive-feed. It might be stuck 
on 0.0. I don't know why, unless you used gedit to do something to 
it recently, but this could be in indication of a contaminated .hal 
file.

Using gedit at my place turned out to be playing with a very bad deck of 
cards.  So I've been using geany now for years, and I sleep a lot 
better. Haven't scrambled a file since.

Hi
One thing that I noticed day before problem with encoder.
I am using m52 to stop feed with 5 vdc that converted to frequency etc,
When I stop feed, machine has changes in few thausands .
X and y axis moved in few thausands but z axis was more quite .
And next day z axis motor stop working.
That may indicate something

Hi
Stuart
Phone is there, maybe even same number but owner different.
I did call few years ago and another company did purchased original
servodinamics.

Motors drive not exactly same. Today owner say that original servodinamic
was very small business etc

Re: [Emc-users] Encoder down

[Stuart Stevenson]

Aram,
I just searched for aerodynamics. I called the telephone number on the web
page. Servo dynamics' phone system answered and told me if I knew my
party's extension I could dial it at any time. I hung up at that time. It
looks as if the report of their demise is a little premature.
Thanks
Stuart

Yes, for AC servos, the encoder has to be aligned to the 
magnets in the motor.

It is servodynamic motor. Company not exist any more.

Maybe the LED has died. Is there any current flow on the power supply
to the encoder?

First, ALWAYS, check for bad connections!  90% of all 
electronic failures is a bad connection.
Check that the encoder is getting 5V power.  What are you 
using to read the encoder position?


I had not heard ServoDynamics was out of business, too bad, 
they made good stuff.

Re: [Emc-users] Encoder down

i did open one motor before, very same type. it did not work after.
i better take motor to some shop.
i think in ac servo motor encoder aliened to magnetic wave etc, and i have
no knowledge how to deal with it.
better some shop - let them see it
this motor has a brake for z axis, but  shaft moves ok.

Re: [Emc-users] Encoder down

i did move encoder cable to another drive , no change number in lcnc, and
move another encoder cable to z drive and number changing.

it is motor encoder not good. that is not repair able so need new/another
ac servo motor nema34

hi
changing number are in linuxcnc where x ok y ok and z axis encoder does not
changing.
my drive linze and led on it ok.
i will swap encoder cable to another drive to see if any change.
