I'm at the same stage with the same suppliers / parts.
SGDH 04AE's and SGDA 08AP's and a variety motors, all yaskawa.
btw, omron rebrands yaskawa stuff so their info is the same but the part numbers are changed ( to protect the ignorant? ) That opens a whole wealth of info that you can cross reference when you get stuck or confused, not to mention a whole bunch of compatible parts that you might not have known was available. Just be careful and double check the details.
I'll get back into the manuals soon and go back through the step/dir stuff, as I remember it was pretty straightforward but might require some basic logic to interface the signals. Simple logic circuits are no problem to breadboard but do add a bit of complexity which would explain why not many people are using these types of drives.
Pins 7/8 11/12 and 14/15 are paired and inverted. Its the first two pairs we need to be concerned with right?
Tonight, as luck would have it, i was looking for that connector for the SGDH/SGDM drives and found what I THINK is the right family of connectors here:
http://www.alliedelec.com/Search/Pro...5B6D00190BE17F
I'm 98% sure its a micro-sub-D type connector. Both of those are the same but with different pin counts.
I was going to go to the local dealer and order some tomorrow so once I get them in my hands I'll confirm that info.
Do you have any details on them that might help me?
As for the motors, they seem to use quite a few variations of connectors but the most common is a square molex type.
If you want to buy pre-made cables, expect to pay a small fortune and have the EXACT part number to connect XXX-motor with YYY-drive (brake, no brake, incremental vs absolute encoders, variety and year of manufacture even seem to change the motor connectors etc etc )
I'm just going to make up my own cables.
OH.. and the encoder cable, at the bottom of the drive is just a USB connector, available at any computer cable supplier.
As for line filtering etc, thats going to depend on your available service, how clean it is coming in, and how much you plan on pulling from it. Personally I think it would be insane to run without some kind of filtering but then again, I'm running 6 axis, all at 400 watts or more and my primary spindle is a 4 KW kollmorgen servo, plus I'm literally at the end of the line. the power line that is. I'm the very last house on the circuit and theres a metal/welding/fab shop upstream from me so my power is terrible. The UPS's on my computers kick at least a dozen times a day.
Hope this helps, and it seems we might be able to help each other ferret out some details and get running.
Anybody else out there been through this?
We know its worth it.
Expensive and tedious but worth it.
Maybe we should just dump them on ebay and buy gecko's ?
Thx
