Hi
I reduced all:
Default_valacity =1.
Max_velacity =2.0
Default_acceleration = 2.0
Max_acceleration =3.0
I reduced most of them by 2-3 times and graph looks good. I will post it
in 20 minutes.
I am interesting why my drive can not output more voltage?

Hi
i should be able to go up to +10V to -10V. Am i right?
is 1.0 output units means i use only 1.0V out of 10V that system can output?
does pic www.conceptmachinery.com/Sh12.jpg looks ok?
This looks better, now your Xoutput is not saturating and the error also
looks trapezoidal. This is a
Aram,
2 PID loops are ok to use, just a bit more difficult to tune.
I use Yaskawa motors/drives with the m5i20 7i33.
I have to tune the yaskawa drive and motor first with yaskawa software and
get them running smoothly.
Usually I tune them fairly 'soft', that is not very stiff (in velocity
mode).
I think the easiest way to do this is for a point to point network or
even a network with a hub is to use raw ethernet packets. An ethernet
packet has a payload of up to 1500 bytes. That should be large enough
for most things we would want.
On top of the payload we have around 20 bytes of
We've had previous discussions about using ethernet for real time control.
In theory, this is NOT difficult stuff. I'll bet I could get something
going in a week or three.
In practice, though, it is a PITA. That's because you would need a real
time driver for each of the zillion or so different

I still don't know what interface you are using, but that MAY be
correct. It would certainly limit your speed if the drive was
Is it possible to use EMC with multi-core processors? I see that by
default the kernel is compiled to only support one processor but what
would happen if SMP support was compiled in? Would RTAI choke?
As multi-core processors become more prevalent, would it be practical to
dedicate one core to

when booting the linux kernel you use isolcpus
(http://www.linuxtopia.org/online_books/linux_kernel/kernel_configuration/re46.html)
Note: isolcpus is supposed to get deprecated in favour of another
mechanism.
Here's an example using cpusets:

Nice. What are the basic config settings you have to do?
How to bind rtai to a CPU?
RTAPI already does this - it uses the highest numbered active CPU for RT
tasks when compiled for SMP.
You need to use a kernel command-line parameter, isolcpus. This is a
list
This is very interesting. I only started thinking about it because I set
up my house machine using the EMC live cd and noticed only one core was
being used. As I don't actually need RTAI on this machine I simply
switched to the generic kernel which has SMP.
