93 Matsuura MC-600V Issue

Hello everyone. My apologies if this post is in the wrong section, please let me know where I should place it if so.

So I have a 1993 Matsuura MC-600V with a Yasnac MX3 control and I'm having a issue with the machine just randomly going into E-Stop and not giving any-other errors.
The issue has started about 4-5months ago, I would happen once in a while and then the more time passed the more often the machine would go into E-Stop for no reason and give me issues, today morning it started happening very often, probably 10-12 times while i was setting up a job on it.

So the scenarios when this happens is when the machine is just sitting there doing nothing or when the Z is moving down(Never saw it happen when the Z goes Up). Does not matter how you move the Z, automatically running a program or jogging, as well it seems to only happen when it goes rapid.

We had that happen. For us it was a bundle of wires had been worn from rubbing.
Depending on how 'wet' the wires were at the time, It would pull down the 24v buss and cause the issue.

Thank you. I will take a look at the wiring.

I have had that happen as well, on a few MC-1000V. Luckily mine were relatively easy fixes. The first was a loose wire on the E-stop circuit. Another was a relay going bad. The last... the operator didn't clean the filter on the spindle chiller and it was clogged with dust. That being said it was a stand alone chiller vs the integrated style and so there was an alarm when I got around to the back of the machine and looked, but the machine didn't show anything other than that the E-stop circuit was triggered.
