Analog controller for servos was created by Nkbhvid
Hi
i am retrofitting a 2002 Homag BOF with Rexroth servo motors and ECOdrive BKC xx.3 040 7 FW.
The setup is originally communicating over Sercos I.
my intention was to use the inbuilt analog +-10v and skip the Sercos. I was planning to use the Mesa7i96 through Ethernet and a daughter card than can run analog communication on the 4 axis.
It seems though that Mesa has more or less abandoned their activities in Europe.
So what are the alternatives to Mesa products?

www.eusurplus.com in Portugal
www.welectron.com in Germany
You would need :
Mesa 7i96S
Mesa 7i83 for analog out
Mesa 7i85 or 7i85S for encoder feedback
or just a single Mesa 7i97T for everything

Pico Systems has the PPMC, a set of boards to read encoders, drive +-10V velocity servo drives and handle digital I/O. It is fully supported by LinuxCNC. Take a look at: picosystems.store/product-category/analog-servo-interface-ppmc/

Thanks
Problem is availability
Welectron do not sell mesa products any longer
Eusurplus is very limited in stock so I fear they are tapping out of mesa as well.
If it’s not sold within EU we cannot use them as suppliers

Pico is on my watchlist.
Unfortunately they do seem to have any dealers in EU.
