so we isolate the problem that could come from the optical encoder that should be connected to spindle by a small belt?

I will check it tomorrow.
Thanks for the help.

I found out that the previous owner had replaced the spindle motor and this one has inside a MZ sensor although the old one had a M sensor, because the plans I have state this.
I checked the cable of MZ sensor and the only problem I found was that the shield is not connected to earth directly, but to pin 10 of the JY2.
I checked the parameters and as far as can judge seem ok.
I can not understand what that would be to trigger the alarm of X-axis communication even if it seems that is something with the spindle orientation.

what show diagnose 200,201,202,203,204 when alarm occur?
Only 2003 X crc=1 and stb=1, all others are 0.
This morning I tried some g84 cycles and alarm 351 continuous and also #200 x dca=1
that means mainboard or option board fault
Do you know how to change the mainboard?
I think I don't have option2.
Attachment 419498
this is my mainboard.
Couldn't reply to your PM. Your storage is full.
Goodmorning

I checked the pulse coder cable, OK.
I added a cable to ground from the replaced MZ sensor (the machine originaly had a M sensor in the spindle motor).
This way the alarm hasn't appeared yet.
Let's see.....
