smdromod success

Thanks,  I figured it was probably something simple.  I've been 
concentrating on the motor drive electronics and I have to make a few 
more boards before I can run more than 1 motor.  I do need to learn how 
to build everything from source.  Playing with just 1 axis smdromod has 
exceeded my expectations.  From my observations I find that I could 
probably lower the pulse output and by recalibrating the Freq. to Volt 
converter still achieve the 240 IPM rapids without giving up positioning 
 resolution.  smdromod doesn't care how many or few pulses it takes to 
carry out the motion,  only that following error does not exceed the 
limits.  Conclusion,  smdromod will work great for me.

There wasn't anymore than a little switching noise and very slight 
vibration from those reverse direction pulses. It wasn't causing any 
following errors so it must have been working. The most important effect 
was those pulses were robbing power from the motor.  Dropping P from 400 
to 360 did eliminate those.  I have yet to find anything even getting 
warm yet.


Many Thanks to all the programmers of EMC.
