Is this mag sensor inside the motor? How do I check if it's providing the proper output? Could that cause the leg voltages to be as unbalanced as they are?

What gets me is that it was running...

Folks,

I have an issue with the spindle drive and motor on my Yamaguchi YMV-60 mill. The machine has sat for a year and a half or more unpowered. Recently I got it fired up. I ran the spindle...

Steel it is. Thanks for the info guys!

How do you verify the sensor in the motor is working properly? My concern is that there is something wrong in the drive itself since the voltage between two legs was around 50 volts, but two other...

I found the switch you are talking about. It is set to the higher voltage.

I checked the resistance between all 3 windings. They're about the same as far as my meter could tell, 0.7 ohms. No winding was shorted to ground. I did find something interesting, however. While...

Thanks for the reply. I took the belts off. No question it's the motor. It's a Fanuc 6M control.

I investigated a bit further this morning. I am quite certain it is in the servo. The link below is a short video of it running. The first half is 100 rpm, then I sped it up to 500 rpm.

All,

I managed to get my mill running tonight. It hasn't run for a year and a half at least. I started moving the axis a little. Then I ran the spindle. I started by running it slow, 100 rpm at...

Update update: I replaced the fuse on the CRT board. Powered the machine up and lo, the CRT works! Evidently everything is ok on the CRT module (for now anyway). Once I connected an air supply all...

CNC folks,

Update: I checked the power unit and have +5 and +24, so I don't think that is the problem. I checked a couple fuses in one of the cabinets and they were ok. However, when I took the...

All,

I bought a Yamaguchi YMV-60 a year and a half ago. The machine hasn't run for at least that long, perhaps 2 years. I put power on it for the first time today. I get nothing on the screen....

All,

I am finally getting around to setting up my Yamaguchi vertical CNC mill. It has 38mm or 40mm leveling screws, but did not come with any pads. My Mazak lathe came with steel pads that the...

All,

I am looking for operation, maintenance, and installation manuals as well as schematics, drawings and parts lists for a Yamaguchi YMV-60M vertical machining center.

Thanks,
Aaron

All,

I have been searching the net for information on Yamaguchi vertical machining centers. So far, I have found almost nothing except a few for sale listings. What happened to the company, were...
