John, Yes, Russ was able to help me out. If I remember correctly, the part he needed was obsolete but he was able to rig something else to work....and it is still working to this day. If you can get a hold of him he can probably tell you more....

Russ, for some reason your email keeps kicking back mine, I get a delivery failure. Have another email address?

Russ, I live in NJ, USA. Please tell me you're in the US too...I would have no problem sending it to you and paying you for it if you would be interested. I just found out a mainboard fried on the machine too so now I have that to worry about. By the time I locate the equipment and all you'd probably have it done lol. Let me know. Thanks for all your help, Dave

Russ, yup looks like I killed it. There is 24v incoming but only mV on the 5v side. Man, I thought I could solder it no problem but wow those terminals are small! ... not sure if I can swing that.

Crap, I was hoping it was something as easy as input power lacking. I am pretty sure I am getting power and ground to those terminals but let me doublecheck. Thanks again Russ. I will keep you posted.

Oh, the screw terminals?? I thought they were for cable shielding or something the way they went to the cables. I'm not sure I checked them so let me start there. Man I hope it is just an incoming voltage problem, that would be great. Thanks so much, you've been a big help already and I will keep you posted.

Oh, my board actually looks like the board on the left above, would it still have the same voltage regulator??

Iaknown,

You most likely blew the small fuse inside the pendant.  Open it up and you will find the fuse in a replaceable fuse holder.  If that fuse is good then you blew the MAX831CWE voltage regulator.  This is a 16-pin surface mount device.  You can actually changes these yourself if you have soldering skills.  The problem is the MAX831 chip has been discontinued so you will have to look for a pin for pin compatible replacement if you determine the fuse is good.  My guess is you blew the fuse.      Hope this helps.

Russ, Thanks so much for the info! This sounds like a start. Unfortunately my fuse is good :-( I had checked it when I took the pendant apart. Now before I go any further, I'd like to make sure I am checking the correct terminals when I say I am getting power. I read 24v between terminals 1 and 7 on the plug, does this sound correct? If so at least something should light up, like the background on the lcd screen right? (it did before at some point). I am good with soldering, just don't know much about circuit boards, so I think I could handle replacing that regulator but have no clue how to find a replacement. First off, what does it look like? Thanks in advance for any help, Dave

Does anyone by any chance have one of the original Yaskawa pendants for this project as pictured above?? I think I just fried mine (I am getting 24 volts in and nothing lights up) and am in dire need of one, or at least the main board inside. Any help will be greatly appreciated!!
