Thanks Andy.

Looks like the YAPSC project is dead then - what a shame.

Hi Larry

I understand the difficulty of making a living at a bench too well! If I was trying to run servos that were integral to the machine I'd very much agree $89 per axis is nothing. However,...

Thanks Sam. Yes, the Viper is not economical for the problem I'm trying to solve - it would be better to buy used step/dir drivers. I'm seriously considering the LCNC/Mesa route, but compared to...

Hello Lucas

Your PM settings won't allow me contact you directly. Just wondering if you ever got any further with your YAPSC - type converter.

Thanks for the suggestions. The YAPSC seems like a good solution.

Having been put right on the UHU servo controller, I need a cheap-ish means of converting step/dir pulses to +/-10 to control some analogue AC servo drives.

Any suggestions?

Thanks David

Thanks for setting me right Bill.

I should have said that I need to control analogue AC servo drivers - so not sure if the UHU controller is suitable at all.

I need an step/dir to +/-10v servo controller. I came across this Homepage Huber which looks like an economical solution to the problem. However, while I have a basic grasp of electronics and can...

I've connected the motor and the encoder. However, I can't get into the servo driver software as for some reason the OMNUC interface software and...

Is special software needed to interrogate the drive via the RS232 port or do you have to have the digital operator unit?

Once again many thanks - you've got me moving along the right lines. I...

Thanks I thought it would be something along those lines - steep learning curve this!

One further thing: I'm used to making up my own cables to connect between various bits of kit (unless cheap...

Just out of curiosity, I take it that the reason why the SGMAH motors, or any other outside of the SGM/P series, won't work is that the encoders aren't compatible?

I take it that the "plc module...

Yes that was a schoolboy error - I know that I need the 02A type, don't know how that slipped through.

Thanks for all your help - much appreciated.

Brilliant, just what I need to know. So I think the following motors will be compatible - let me know if I'm mistaken:

Thanks for the reply. Full model number is Omron R88D-UA08V - 200V 200W.

All I really need to know is what is the equivalent series of drives and motors - I can work the rest out for myself. I...

I know this is a really old thread, but can anyone advise the Yaskawa equivalent of the Omron R88D-U drives and R88M-U motors?

As mentioned in my begging thread, I bought a couple of the above drives. I know that any of the Omron R88M-U200 motors should work with these, but what about other Omron R88M types or is it just the...

I just took a punt and bought a couple of Omron R88D 200W servo drivers (R88D-UA08V) very cheaply and wondered if any kind soul here had a spare motor I could borrow for a few days to see if they...

Still fretting over which drivers to buy. Good advice on here to go with Leadshine AM882 but I have to say that I take on board Jame's counsel and I don't feel at all confident about buying from...

Many thanks Gerry. I'll do a little more digging!

If I do I certainly will post my findings here.

I'm just surprised that on this and any other forum there doesn't seem to be many who admit to using the cheap drives successfully or otherwise...

Hi James. Thanks for taking the time to post. I actually watched your video a while ago. I'm aware of the issues with buying direct from China, but I've had greater problems with UK based eBay...

Thanks for the advice James.

However, I don't think I've really got much choice in the UK. You're spoilt in the US with having a number of home-grown manufacturers - just about everything from UK...

Thanks for the replies. How do you find the quality of the JMC motors and driver?
