That is exactly what I am doing!

I will update with results....

Thanks, Al, as always.

So if I am looking for "ground", this would be N, P, or T?

I ask because I have given up on the Fanuc and I am installing an Ajax controller. I need to install new...

Today's question relates to encoder wiring.
In the following, which is ground for the +5V?

Is it H? Or is it N or P or T?



Thanks,
Christian

Inspected X and Y servomotors today. Y needed some cleaning up... resurfaced the commutator, but that didn't do anything for the overload message.

No, not by me anyway.

In extremely simple terms, the story goes as follows:

• Machine powered up fine five years ago, with this phase converter (although I did not know how to program it).

•...

Thanks in advance for the schematic.

No, the machine does not come into the ready state. That's the whole problem.



This is all I can get on the screen for the last few months. This is...

Hi Al,
Thanks for your suggestions...
I want to understand what you are saying, but I really don't....



By this, do you mean disconnect the 4-pin connector which supplies the power to the...

Thanks Warren-

Very nice offers on your part.

Although I have considered the idea that one of the VCUs might be the culprit, I have no idea which one it might be. For that reason, the idea of...

I'm slightly confused....

Al, are you saying that Warren is not correct in his thinking about the phase converter?

It IS true that I successfully powered up this exact mill using the exact same...

Well, the machine was in fact phased incorrectly. I was confused by the fact that it currently has a reverse-helix end mill in it. Anyway, that is sorted out now.

But it didn't change anything....

I have spent quite a bit of time today with this frustrating machine.

I re-soldered some .016 wire into the "flag" fuses, thus repairing the three that had blown. So far they have not blown...

Also, after inspecting one of these fuses, I've observed that the "signal" blade of the fuse (the third blade) functions as a switch, and is in the open state when the fuse is in good condition. ...

OK, thanks Al. I understand.

However, when I started messing around with the machine a few weeks ago, all my fuses were intact! So I am doubtful that's the problem. And the fuses keep on...

OK, thanks. The battery certainly does show signs of being dead. But would that cause the kinds of problems that I am having with the servo overload alarm?

I checked the thermal switch leads...

OK, so the VCUs which have the parallel fuses setup are in fact for later model (larger?) motors, (motor models 10, 20, and 30). My motors are model 0, which makes sense since I could not find the...

OK. What is the MS connector? I've got two connectors to each motor, one 4-pin (of which only three pins are used) which seems to be power from the VCU to the servomotor, and another connector with...

Thanks for the reply.

I just spent some time in the shop with the machine and looking over the manual.

I must have a different manual than yours, as mine says nothing about thermal switches on...

Oh, I really want to believe that... but I have never had anything but problems with this machine. I have had so many alarms and over-travels and power supply problems that I have never even gotten...

Wow, thanks for replying, Al. You are the first person to reply.

I recently replaced the main power supply board, and got it to power up, but I am now having an error message (I can't remember...

I purchased an Enshu Yuasa AccuMill 1547 with tool changer about eight years ago. This is my mill:
