Re: emc help

Hello,
Whoever wrote this doesnt know much about encoders.
I use hiedhain encoders and they are expensive but they have a max
encoder freq of 300khz which is double the normal spec of most other
encoders.

The only exception to this i have found is laser encoders made by
canon.(Way to expensive)
Also if you check your specs on the STG board the max enoder freq is
not 10 mhz but much lower.

And of course the parallel port could not run at these speed.
And even the pico systems is limited to 300khz

Regards,
Greg
