I have an older tree mill and just had another drop into my lap. What I didn't know was that it is a 10k spindle with an oil cooler. My other is a standard 6k greased sealed spindle and both came...

interesting work around..... I added a .005 radius to the corners for the second pass and it worked flawlessly.....

I'm running a Tree mill with a 3M-C control and today it's doing something strange. Cutting a rectangular profile with a 1/2 endmill with 2 passes. First pass the machine picks up my cutter comp and...

Does anyone have experience turning, drilling M4 tool steel. I have a customer that wants some dies made. I've made them before out of S-7 but now their wanting the wear resistance of M-4. I'm...

I could'nt seem to find a place to post this, so I'll put it here first. I'm getting ready to part out a Hitachi 304-P with the auto wire feeder. It has the fanuc 6m control with the 230sp power...

Yes I have the same machine but with the auto wire feeder attachment on it. From what you describe it sounds like the board I was talking about in the side.
Right side of the control, behind the...

First: does it run a dry run of the program?

Second: does the machine edge or center find? that uses a transient voltage around 20 on the meter?

third: if you have the auto wire feeder you...

I've got the same machine, what seems to be the issue? I do have some of the manuals but have not found wiring diagrams specific to the internal boards.

continuity between motors and drives/encoders is fine also. I'm not sure about between drives and control though. I don't have any wiring diagrams and trying to chase them through the cabinet seems...

OK I've tried almost everything I can think and all the suggestions and no change. Still a 403 servo alarm.

heres my list so far;
1 checked all motors, tachs, and encoders (excellent shape)
2...

I have a hitachi H-cut with the 6m control and at one time it was doing the same thing.... ran great then would not move in a feed move unless it was in dry run. tried all those other suggestions and...

I have a 6m control with a 403 servo error. I don't want to have to start buying drives until I can say which on is faulty or if it's a drive at all.

Does anyone know a technique for narrowing...

I'll check that today. I went through and checked voltages on the pins for the x and y drives and my 24 volts reads 27v. Is that enough to create an overcurrent condition?

Is there a way to...

I've poured through the forums on this topic and I'm still having trouble. The machine is a Hitachi wire edm with 4 axis. 2 (x,y) are common fanuc a06b-h001's and the other two (u,v) are much smaller...

I ran a FX-10 for 5 years. AE function was great, seal plate is a non-issue if cleaned weekly and the only errors that paused the machine was die-electric and all you have to do is pull the sensor up...
