Mitsubishi Mr J2 40A Motor Drive | eBay

SOLD!

Hi All,

I've got a surplus of these drives after upgrading to the J2S series of the same drive.

Here's one for sale. I haven't decided if I want to sell the second, but if someone wants both,...

Excellent. I predict your problems will subside.

I am very leery of running any 208V input equipment on a high leg delta. Those stupid things were originally designed for lighting loads and 3PH motors. The trouble is that a CNC or anything with a...

I'm starting to feel sorry for you...I'd be all over the PoCo since it sounds like their feed is doing your equipment in. :boxing:

I found an arcing fuse on a feeder in my neighborhood by tuning...

I wonder if your center grounded delta is sometimes an ungrounded delta! No amount of grounding on the sink side (machine side) will help you avoid a massive phase current imbalance.

Because your...

Somewhere upstream you have a loose wire on the transformer secondary (POCO), a weak breaker or loose lugs in your building.

Here's what I think is going on. At start up, the surge current is high...

Almost a full year has transpired and I never heard from Peter Hohmann again after a single email that said "I'll get you something next week" - yeah, right.

I can't help but think you treat your...

Bumping in case Mr Hohmann sees this.

Three months and no replies at all... :(

Ok, I guess I'm on my own again. I don't mean to rush, but I don't think an quick reply should take three weeks. I'm not asking for spoon feeding, just an amount I can send to get bare boards and a...

I haven't heard anything yet? Spring is just around the corner which means I can start getting some of these projects out of the way.

That's not correct. The DMM product is not a back EMF protector...just a fat filter capacitor. dustincram has a nice product for a specific problem at a good price. I have no related interest, except...

Excellent progress. I've waited almost two years for some movement on this.

I have the bigger brother to that one, the IJ750-LN. Would you let me buy your firmware/Gerber files to build my own...

Wow. I love eBay. I just bought a 40A for $99. :banana:

I love answering my own questions. :rolleyes:

I have 8 MR-J2S-40B drives. I'd like to convert them so I can use them with my Step/Direction controllers.

The first thought was I could swap an IC or two to convert to the 40A version:

Is...

I ended up repairing my drive. It appears that it got wet at some point, but the damage was limited to the input circuitry. I simply replaced a few resistors and decoupling capacitors and it's back...

I purchased three of the 40A's last year and just now got around to using them. Turns out, one has a problem (and is even marked 'BAD') - but I paid fair market value for it. Upon opening it, I found...

I just wanted to check and see if the OP found a way to interface his Mitsu drives with Mach 3 effectively. I have the same drives and I would like to know how you are able to connect the Mitsu to...
