Here it is 2014 and I find myself downloading your models so I can use them in ProE with a horizontal router machine design! Thanks!

Seems that I only update that once per year, now is as good a time as any!

I have made a bit of progress on these little beasties, from a physical layer side, but not much / anything from a...

Did you every get any data on these guys? I'm making SOME progress lately, but not much in the way of decoding the data returned.

Well that sucks! I had a long reply typed up and hit the wrong damned button and lost it all!

Well, the short version is I have made a bit of a break through with these encoders. The do appear...

safarir,

Is this with a Kawasaki M21 encoder or the Sanyo PA035 (I think) absolute encoder?

I have FINALLY been able to spend a bit of time digging into my M21 encoders and this is what I...

That could be one of the serial encoders. I have several with the Kawasaki version of that (M21 encoders). They are small diameter (say about 1 1/2 inches) and only have four wires out (VCC, GND,...

I'm more interested in getting this one up and running. It's more of a hobby project than a get tool up and running project.

I have tore into the drive today. The module is a Tyco P483B03 IGBT...

Sorry for bringing this back from the dead, but did you ever get an answer to this question? I am in the same boat.

Tell you what, I'll forgive you "bad english" if you forgive my VERY tardy replies to my own thread!!! ;) And my English probably isn't much better either!

Right now, I am (SLOOOOWWWWLLLLYYY)...

safarrir,

The encoders are definitely SIMILAR, but also definitely different. Definitely a completely different PCB as well as my encoder is only a 4 wire (5V,GND, A+,A-). I have a LITTLE bit of...

Some new info, but not much at this point. I received a call from a sales rep from Kawasaki Robotics. From talking to him, it appears these motors are all off of a Kawasaki Robot. These motors...

Yes, I can take a pic. I'll post that tomorrow. It has something on the board that looks like either a super cap or a battery, but I haven't dug deep enough yet to figure out which. Maybe that is...

Steve,

So far, that's the only bit of information I have found also. I think I will try sending an email to both Mitchel-Electronics and Kawasaki Robotics to see if anyone is willing to share...

I have been able to dig out more information on this thing. As per the back label, it is a Kawasaki M21 serial absolute position encoder. They are 8,192 count/rev (13 bits of data) with a shaft...

While digging around that web site, I found a TINY bit of information on the PA035 absolute encoder. The picture is VERY poor quality, but the picture of the top of that PCB looks EXACTLY like the...

Mike,

Thanks for the slap up side the head! I did a LOT of google searches, but I never even THOUGHT of going straight to the source and seeing what they had!

I'm even worse! They do appear to be correct and the pics you posted look exactly like mine.

A single RS485 stream can carry all the information needed to fully decode that wheel, even at 4500 rpm. It would definitely have to be sent as data instead of raw bit levels. So yes, it only has...

Stranger and stranger. I did a bit more probing and found a couple of other interesting bits:
1) There is a voltage regulator on board. The MAX417 is getting 2.8V (within spec of 2.5V min) at...

I dug a bit deeper into it. The servo has an integrated brake, so I had to apply 12V to that before I could even (easily) turn the shaft. The encoder itself is a three track unit with some very...

They are definitely NOT low resolution encoders. There is definitely a high resolution glass encoder wheel in there and a LOT of SMD electronics packed on both sides of the board. None of that...

Folks,

I picked up 6 Sanyo Denki P5 servos for a VERY reasonable price, three 100W and three 1kw servos. They appear to be almost brand new, which matches the description of their previous life...

Thanks Lucas!

Folks,

I have a EAD LA34AGK-26R stepper motor I picked up from work (they were tossing it as it was an unneeded spare...). It's known specs are:

EAD LA34AGK motor
NEMA 34 class
Hybrid motor...

What all signals should I expect from an encoder? So far, I have found what appears to be three sets (push pull from RS232 chip) of encoder outputs (I only expected two...) and what appears to be...

Ouch! 111 looks but no one was able to help... Oh well! That just forced me to tear the thing open and spend some quality time with my bench meter and my scope to see what this thing does. I have...

Gents,

I picked up a Panasonic AMKB100G20NAL AC servo motor off eBay (very cheap!), but have not had any luck finding any data sheets on the drive or it's encoder (drive is simple, encoder, not so...

True. But the servo controller DOES read the encoder signal. And it DOES respond if the servo did not get to the next "step" when it should by increasing power. AND it can signal if they are...

Too True! I'm part Apache and part Comanche myself...

Sigh.

Man for man, they were MORE destruction to the environment than the Europeans that replaced them! The only way they "live(d) in harmony" was because their numbers were so low and they were...
