Hi everyone, We are planing a spray system on a X-Y-table and want to control it with EMC. We want to use servo motors. When I see it right a common setup is to use for instance a Mesa 5i20 board and a 7i30 H-bridge. My question is now: what cable lengths are possible. I guess the H-bridge should be close to the I/O card i.e. PC. So I have a long cable between the H-bridge and the motors. What lengths are possible there?
Just a thought I had: wouldn't it be a good idea to bring the H-bridge close to the motors? Then you need a different link between the I/O card and H-bridge. The 7i43 supports the USB port, but there I see some problems with the realtime, right? But what about the 5i21 I/O with a 8i20 card and a serial RS-422 link between them? I know, it's not support at the moment, but is it possible in general? Or is there something I miss? Regards, Kai -- Schaeffer AG Dipl.-Phys.
