I jump 9 and 64... the LED lights all go off. the error however now is 404 alarm.. VRDY ON...

the way this all started was like this..

Back in Feb of this year, the mill was powered off for 2 months. It lost its parameters. I managed to get it going again, but then it started having issues booting up. it would hang at the PLC version, and I would have to power back off and on.. Then about another month later, it started getting the 401 alarm, but I could power off and on about 5 times, and it would go away. Sometimes it returned when I touched the Z axis, sometimes it was when I touched the Y axis... but NEVER when I touched the X axis... well, power off and on about 5 times, and it would clear.

Then in July of this year, it went to 401 and never came from that. I moved the servo motors around, and this did not make the LED change location. I changed the X121 X131 X141 and this did not change the issue either.

Today, when it boots after being off about 1 hour, it will come to the ready state and sit there about 5-8 seconds like it is ready to work.. but then once the 401 alarm happens, every time you power off and back on it trips the 401 really fast.. 1-3 seconds. Let it sit about an hour, and then again, sits there like it is ready for 5-8 seconds.



The "speed controller amplifier at maximum" is a strong indicater that you have a faulty tacho or cable. The tacho will give a DC volt reading if you spin the motor. 2V for 100 RPM. This is a way to check the tacho. Depending on the size of the motors, you can spin them manually with a big drilling machine. Just remember to disconnect the power and motor before you do that. Some tacho's are multipole DC generators with Carbon brushes. Check the brushes if there is any.

Whacko

I have lots of cool tools...

I cannot read those schematics from siemens... the voltages are not marked what they are suppose to be, and then in the reading part, it only references to things like the DC Link voltage, but not where it orginates, and terminates..

seems that the fault is "speed controller amplifier at maximum" V2 , V6, V10 at card N1.

I have read the voltages at G0 on 73.1 and 73.2 and 72.. they are :

9 = 19v DC
64 = -1v DC or 1v AC... cannot decide what it is suppose to have.
72 = 24v DC
73.2 = 0v - .2v DC

thank you for your effort and help..

I only have a eStop.. no pause button..

i will jump 64 an 9 be ready.

I power the machine down completely with 3 phase cut off completely. The Fanuc barely keeps its own parameters, I dont think it is holding the fault code for the Siemens drives. This is a model 0M-A... very old everyone tells me.

Yes, thank you for the PDF.. I had that one from Siemens site.. I however was told it was not for my drives at one time, but I see today, that it is SimoDrive 210 I have.

I thought you were Bill in TN when I got your email. Sorry about the strange return email I sent.

Yes, I have LED's on what is G0 V1 ( red LED ) then N1 V6 ( Y axis ) ... I have checked all the power, but I cannot find what the outputs/inputs at X121 are on the G0 card. I think this is the problem area.

thanks for your help..

General Mach Discussion / Re: Simple Wiring Problem ???
« on: December 05, 2007, 05:04:43 PM »
Well, I can only wish you luck..

My mill is dead and I have no manuals for the wiring :(

I have purchased alot of the PC to CNC hardware already, but I wanted to use my servo motors, and I cannot find schematics to the motors :(

I can wire if I have a path... no path :(

What do you find to be the hardest part, longest part, figure out part on doing a RetroFit of a Mill, lathe, router.....

Today, I have a problem.

I started researching this retrofit of my CNC mill about 2 months ago. First, it was try to fix what is there.

IF anyone here can give me insight to what is wrong with my mill today, I will happily pay you $100 at least with paypal or MO, and even more if we have long conversations by phone or emails... Why do I want to fix what is there? I have a WebbMatic 800. Its interface is Fanuc 0M-A with Siemens drives, and Siemens DC brush motors... My problem is in the Siemens drives. I have a fault at V1 and V4, and this is causing the 401 Alarm : VRDY not ready.... I have voltage to the Siemens drive. So it is not a fuse or transformer issue.

Now to the orginal topic... So, I set out to get a PC  based CNC conversion. I have read about these for several years, and being a networking computer guy, I loved the idea of using a PC based interface. However, I did not understand what a Fanuc controller really was either, except some special PC mother board with deciated tasks. Now I understand this hardware a little better today. I like my Fanuc interface, but being a 0M-A, it is extremely limited on what it can do. However, my projects are not even complicated and this can accomplish what I want to do today.

I still read and read.. 1000's of hours in reading all the various forums. Watching Galil videos, ordering Centroids, AjaxCNC videos, Camsoft, and anything else I could find on information. They all talk about each piece just enough to make you want it really bad, but they want you to buy from them, and get all that great tech support.

So, I purchased a Galil DMC1880, and DMC1740. I have the interconnect 1900 and the 2900. Purchased some AMC drives that can handle DC motors up to 190v... Ok, how to wiring.. I cannot find anything about my Siemens motors. They are General Numeric branded, but I have been told they are Siemens. The encoders on the back have about 8 pins. There are 2 DC power wires, and then 2 other wires in that same junction box that are really small. I have been told they might be brake wires.

I wanted to use these motors. The cost of motors for my mill is at least $800 per motor, and most want closer to $1000 per motor.. If I had schmatics to these motors, I think I could figure out how to wire them to the AMC drives.

BUT... today, I decided that if I can fix the Mill like it is, I want to build a CNC plasma table and install all the stuff I have purchased to do this. I already have a Miller plasma cutter. My hand is not steady enough to cut nice straight lines, so I can just build a X Y with a manual Z and connect my plasma head to that. I am enjoying to learn this PC based stuff, but I really need my mill running today. The motor issue is killing me however with the cost of what it takes to run this large mill.

thanks for any helping coming........

So, what is your story out there about what was hard to find / do / learn?

Well, at the bottom of cnc4pc.com there is a Mach3 ad.. so I would email to them and ask if it will work 100%.. My guess is that it will.

General Mach Discussion / Re: MACH3 ROCKS !!!
« on: December 04, 2007, 12:46:37 AM »
Newbie here toooooooo on the Mach3... while I have not even turned a motor shaft with it yet, I have managed to get it going on my Dell GX1. I have my Galil 1880 installed, and it is even the Rev E card with the PnP chip on it. It took just a bit to get it registered, but it did, and Mach3 appears to be talking to it, and it thinks it is sending commands to some thing.

I have a motor plate that is less than 250 lines of code, and I could cut that for 6 months before it got more complicated for FREE it seems like. However, with the support of this forum, and the emails from the Yahoo groups on this product, $160 is a steal.

Thank you Art and others involved to the development daily, and to this forum for the sharing of the development from your side.. makes a newbie coming in feel real welcome.

General Mach Discussion / Re: why is mach suddenly doing this?
« on: December 02, 2007, 01:32:44 PM »
Seems to me that after reading some of the posts by Darrel Merrel.. the tuning of the drives to the motors makes all the difference in the world with how tight the machine stays on tolerances. you can see some of his posts here . http://www.machsupport.com/forum/index.php?action=profile;u=6676;sa=showPosts

are you using a Galil?
