so if you try M19 several times will generate the alarm?

[magzi]

Every time, but the time the alarm follows it varies from 2 sec to 10 sec.
I found that my machine has a M sensor and a position coder because there are cables connected to JY2 and JY4 ports of the spindle amplifier.
My spindle motor is A06B-0854-B100 and the amplifier is A06B-6078-H211

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

[magzi]

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?

[magzi]

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
