Yaskawa Servopacks any good?

I saw these servos and drives for them and wondered if they were worth grabbing to get to learn how to play with servos. I'd be using them on a parallel port initially. Seemed cheap enough and I don't see many servos in my part of the world. He links to the manual in the listing.

Maybe 2 of them could go on my lathe eventually.

Those drives are rock solid. You can't break them. Make sure the command interface is what you want. They have a few different ones and the mechatrolink is a big "stay away".

I have yaskawa drives on my big machines and I wouldn't have anything else.

They are easy to work on and not expensive to repair that model type. So just make sure the control interface you can use +_10v, and you will be happy.

Oops I bought them. There will be many many questions to come. Looks like the manual he linked to was wrong but I found the right one. No Mechatrolink! So the drivers say they take 110 volt. We have 240V in Australia. Do I need a step down transformer? If so should it be isolated?

Thanks Bevins

WOW. I'm surprised, they are usually all 220 volts. I never seen one at 110volts.

You'll be happy with them.

Post the link to manual. I'd like to take a peak. They usually use active low so be careful, you'll need a ground to enable and low inputs.
Whats cool is they have a Pot and Not, and your Limit switches go directly into the drives, not linuxCNC. The drive lets you jog off in the correct direction but not the other way. Do the soft limits thing in Lcnc though. They are cool drives......

50W motors ?
I have used even smaller ones, namely 28W ones. With some reduction they can do plenty of things.........like moving a coffee cup closer to you !

at 3000 rpm I wonder if any coffee will be left in the cup! Yes I saw they were tiny by the torque rating but good to train up on for when you show me how to retrofit a lathe

I think this is the manual

Pretty scary reading

I saw this 240-110 V isolated power supply. but I am sure there is a cheaper way. Non Isolated version is about $90 from these guys.

I'll be watching your Mazac build...

I've got this lathe, now with a DRO, swing is 13"



I made the stand after this happened. Had to rig up a block and tackle to stand it upright as at 280kg we could not lift it.



Anyway, I have been thinking of getting a little lathe with 80-100mm chuck for a CNC experiment, maybe these will run it. Something like this and it already has electronic speed control on the spindle:
