YASKAWA SERVOPACK Speed-Control instead Postion Control

Now have ordered a 7i97 and when it arrived then i write a connection plan for the Yaskaway - hope i can use some infos from ehb - and share for discussion.

Hello,

Mesa has so many cards, it's sometimes hard to really know them all. A comparison chart or something would be really nice..

Thanks for the overview of the 1CN connector, I didn't have that!

Looks like on my machine, "S-RDY" is connected to pin 27, which supposedly gives out GND when the drive is ready (sinking output). Pin 28 should output + then (sourcing output).

So in return this means when using pin 27, the input should be sourcing type and when using pin 28, the input should be sinking.

Please correct me if my thinking is wrong.
Since I already have the 7i77 standard sinking input type, it means I'd have to move S-RDY of the drive from pin 27 to pin 28?

We'll figure it out, thanks for bringing this to my attention. I was under the impression my machine used sinking inputs to begin with.

Hello ehb,

i have wrote a link to the pdf with this datasheet with this CN1 Connection in the upper posts - here for you again:
www.nighteagle.de/Yaskawa_CACR_SR.pdf
Hope it will help...

Do you have the identical yaskawas or another Type? Because the CN1 Connection is onaly for this Yaskawa - i have another datasheet for the P-Version and it is total different... So be aware of using wrong datasheet!

You're right, they're not exactly the same! Sorry, I didn't want to cause any confusion. Thanks for pointing that out!
My machine uses: CACR-SR20BE 12G (X), CACR-SR15BE 12G (Y), CACR-SR05BE 12G (Z), CACR-SR02BE 12G (C).

So the manual you have is for the CACR-SR**AC and SR**AE type, and the pinout has some differences. However, S-RDY- and S-RDY+ remain on the same pins (27 & 28). I found a manual for my type ( Link ).
 

Are we on the same page about sinking & sourcing of S-RDY signal by now?

Hey I have done several yaskawa servo retrofits to Linuxcnc

I found I had to use torque control to get good enough accuracy and power

I'll try check back here later to see any replies as I can probably save you some time

Hello Becksvill,

you are welcome - i'm waiting for my mesa-card then i think i have so many questions
But for now i will first take the connection.
Have you some special informations for the connection of the yaskawas to mesa cards and configure in linuxcnc?

Regards,
Philipp
