I had the same problem and was so fed up with nuisance trips I isolated all my limit switches with Allen Bradley slimline din rail mount relays. 24vdc out to limits, return to activate the slimline...

I use those drivers, only they're leadshine DM2282's. They work good driving my nema 42's on my plasma table. 240VAC in and just out to the stepper. Made wiring a lot simpler in the cabinet. ...

Pm me your email and I will send you the parameters. I have them copied off in a pdf file.

I would not purchase it unless you were planning on retrofitting it. The ONLY way to make it worth anything is to retrofit it. I drip fed the original controls for a while and it really was...

I did one of those that I own about 8 years ago. My original boss 5 controls took a crap and I wasn't going to fix it to keep drip feeding it lines of code so I decided to upgrade the controls also....

I recently replaced my Mitsubishi FR-SE spindle drive with a Hitachi SJ700D cause repairs were going to be too expensive. Its in a Leadwell MCV-550E. I have it hooked up and all is good on the...

I have had the Hitachi running for a while now and it seems to be performing well. I have ran a 3" face mill at .040" and it took it fine, drilled some large 1" holes and ran a boring bar for a...

I thought about chains too but ruled it out cause my table is 18' long. That much unsupported length of chain would be problematic I think. Chains are not generally thought of as a anti backlash...

I have a Leadwell MCV-550E that I just replaced the FR-SE with a Hitachi and have been researching replacing the CRT with a Lcd monitor. My CRT monitor still works but I would like the availability...

I use 25mm timing belts for my cnc table and don't have any problems with my setup but it depends what you want to do. I just plasma and torch out weldments so +-.010 really doesn't matter to me...

I have decided to go a different route and replace the FR-SE 5.5 with a Hitachi SJ700D-075LFUF3 VFD inverter drive. The FR-SE is a 5.5kw 7.5hp drive and the spindle motor says 32amps on it so I...

I got the power supply working and tested all the outputs on the power supply. All the outputs on the supply are within specifications so now I'm looking at the seio1 board. I replaced some...

I wish my power supply was that simple and one board. I have a SE-PW and not a SF-PW. The SE-PW power supply I have is two boards linked together with about 3 dozen yellow wires connecting them...

Hello Vavco, Have you checked the firing circuits on the drive, It sounds like similar to what I had with the orient problem with mine. My motor made some strange noises while trying to orient or...

I also have had issues with my FR-SE 5.5kw freqrol drive. Its in a Leadwell MCV-550e with Meldas M0 control. A few years ago I couldn't get it to work properly while orienting. I turns out I had...

I have a Leadwell Mitsubishi Meldas M0 controls. Are they some weird Chinese characters? When mine did something similar to that the battery was bad and lost all parameters. I put a remote battery...

Do you have the original machine parameters book? That will help to know what to set the controls to. PM me your email and I will send you some tech sheets that I have.

Just a update. The diode I purchased FAP800 - 50w-805.0 laser package works great for cutting paper and similar things. It will etch and burn wood which is what I was looking for. I am running it...

Hello, I have the exact same machine that I have been running for over 15 years now and may be able to help. Did you do a ram clear when you powered it up? And did you enter all of the parameters...

Hello all, I am building a cnc table / plasma cutter and decided to put a laser on it in the meantime. I purchased a Coherent FAP800 - 50w-805.0 laser package and was wondering if anybody else uses...

I couldn't find a easy workaround for running NC Link on a 64 bit system that didn't take a lot of configuring and setting up to run it so I opted to buy a small form factor computer off Ebay. It's...

With all the older machines out there and the limited memory storage that they have I would think that quite a few people use NC link to DNC their machines. So my question is has anybody found a...

Hello all, I am looking for a rotary table 8", 10", or 12" with a 72 to 1 ratio. Does anybody make one this large in this ratio. I have been looking for quite a while and have been only able to...

I believe a M50 control is different than a M0 control but I have never seen a M50 control. Someone please tell me if I am wrong. I can send you the parameters for my M0 control if you would like...

I have some parameters for a 1986 leadwell MCV-550E with mitsubishi meldas m0 control. I have my original manuals and some scans from them if that helps. I need help with more memory cause the...

Hello, I have a older Okuma Ls manual machine that i need a little help with. I believe they actually call it a LS-540mm by 1500mm. Im also not sure but i think its a 1964 model with a serial...

Its running again, after replacing igbts, diodes, resistors,transistors and 3 of the hybrid IC's. I'd like to thank all who helped, it is greatly appreciated.

I have replaced two of the 3 igbt's in the back. One had a large crack in it and the other tested bad. Also replaced some 100 ohm resistors, diodes and one c2939 transistor just to be sure i got...

I have a mitsubishi freqrol fr-se spindle drive that let some smoke out the other day. I checked all the components and replaced the bad ones except the dk434 hybrid ic on the se101board. ...

I have a leadwell mitsubishi with meldas MO, MCV-550e with the parameters if thats what youre looking for? send me a message if thats what you need.
