Toranacar,

Hard to tell, it could be your main connection... but it is in an awkward spot IMO. Are there other big terminal blocks in the other cabinets?

Joim,

Does your machine have a 2 speed gear box driving the spindle? I can get you parameters and tool change programs this evening. It may take me a day or two to pull the Keep-Relays, Data,...

Joim,

What machine do you have again? Would it be a Shizuoka Millmaster B5v? If it is a mill I'd expect the controller to be an 11m. If this is the case... I have a Millmaster B7v with a Fanuc 11m...

Fadal,

Sounds like the contactor is working.. as it is passing power to the drives which are then charging up. Time to check some of the other inputs on the drive to see if they are getting...

Fadal,

Any luck with getting the servo drives powered on? Is the contactor coil getting power? I can't help but wonder if the ATC and the servo drive problems are connected. I seem to recall...

Fadal,

Contactors are mechanical and subject to dying... if the contacts were on the way the out, then continued use of the machine may have just burned them out that much faster. Replace the...

Fadal,

This looks like a much newer OM.. As to where I would go.. Check the incoming power (L1, L2, L3 on the right unit) and in the case of no power - work backward to see where the power is...

Fadal,

Might be time to reconsider the handle.. Fatal Error ;) . I looked at one of these machines a while ago.. As I recall it has an "all in one" servo controller. I would guess one of two...

Fadal Error,

Your welcome... your description of the problem sounded like what I saw when I first ran my 11m (first program I ever ran was 3.5Mb, machine's memory is only 32Kb). My machine is an...

Fadal Error,

I like your handle... check your computer... You need to get into the device settings and find the serial port that you are using. In the options (maybe advanced options) for the...

toranacar,

I have liked DNC4u. Not to expensive to buy and you get any updates for free.

Fadal,

The cnczone search engine is too simple to find the attachment.... If you go to duckduckgo.com (or the google) and enter in the search bar you'll have better luck as this will force the...

Fadal,

Possibly a blown receiver chip in the control for the input you're trying to use. Look for a O_Serial.pdf here in the Fanuc forum.. I'm not sure if you can search fro it directly. I have a...

Erik,

I got lucky... as I have a native 3 phase drop to my garage (480v no less - the city inspector freaked out when he saw that back when the water company switched from tubs to a pad...

Erik,

While I'm not sure that the RPC is the cause of what you are seeing... rotary phase converters do not create balanced power. At idle, perhaps, they get close but as soon as you hit the RPC...

Bob,

What else is on the rung with the G0043.5? There must be a contact on the left side of the ladder to energize the G34.5 coil even if the contact does not have any means by which it can be...

Scott,

Yes you can program in a counter... you don't even need a macro to do it. You have the basic idea already. I just did this a couple of months ago to cut 31 splines on a shaft. I'll post the...

Scott,

I don't think you need a limit switch... you just need to fire x20.2 for a second to have the mill continue on. A relay or mosfet transistor output on your Arduino would work. Using the M40...

Erik,

I'll second and third EME's advice on capacitors. I posted this a while back on this thread: https://www.cnczone.com/forums/fanuc/285368-fanuc-6m-power-supply-a14b-0061-b002.html .

Jon,

I believe Centroid has a servo controller that will run the old Fanuc drives. I think you need to replace the encoders. The only problem is that you'd probably have to install the rest of the...

Rem,

It may not be just one capacitor.... I would recommend pulling the power supply and replacing all the electrolytic capacitors... This is in post 17 on this thread but I'll copy and paste it...

ok.... Does the machine have a bunch of contactors in one of the panels? It would be interesting to disable all of them - and hook them up one by one until you find your problem. One last thought -...

Hmmm.... well that's the end of that theory... What other loads are there in the machine? Is there a hydraulic unit? Spindle cooler? Tool changer motor? As Jim points out you can't dump 6200 watts...

Mini,

When you say that you have disconnected X, Y, Z and the spindle - have you only uncoupled the motors or have you pulled the power to the servo amplifiers and spindle drive as well? Have you...

Chips,

Write protect... does the machine have a write enable/write protect key on the panel? Or around the side?

Chips,

Some of the 10m were configured without the dripfeed/dnc capabilities. Read through this: https://www.cnczone.com/forums/fanuc/112267-fanuc-10m-drip-feed-5.html#post1945206 Tonight I'll...

Chips,

I don't have one myself (I have managed to keep (so far) my 480v 3ph hookup to my garage)... an electronic phase converter (like a phase perfect)? My buddy has one and is pleased with it....

Chips,

https://www.cnczone.com/forums/fanuc/273710-cnc.html <-- this is the post I was thinking about. Look at post #10. I'm willing to bet a few doughnuts that your rotary phase converter is too...

Chips,

How are you powering this machine? Are you running this on a Rotary Phase converter? Another member here had a similar problem and it turned out that the rotary phase converter was half the...
