Re: emc help

Hello,
I had already planned on settng an external plc to acount for emc's
dismall i/o control.
My estop circuit is already integrated,thru a watchdog,drives,etc.
Having a 10 volt command while your computer is hung would be a bad
situation.(can you say crash)
Since you seem to be knowledgable about emc
What is emc's top feed rate given a .0001 resoultion from the encoders
(with a 2ghz computer)
2 for a multiple axis interpolation
3 for a point to point traj
Regards,
Greg
