Greetings PCW; 

According to what I am seeing with a halmeter, the 7i76 completely 
replaces any need for a pwmgen to be included in the hm2 config line of 
the hal file, thereby simplifying ones hal file by quite a few lines.

However, with a vfd to control, it appears there are 3 parameters to be 
added and serviced with setp's:

hm2_5i25.0.7i76.0.0.spinout-maxlim
hm2_5i25.0.7i76.0.0.spinout-minlim
hm2_5i25.0.7i76.0.0.spinout-scalemax

However this does not disable the spindle if the requested speed is below 
minlim.  Shouldn't it?

I'd appreciate some guidance in setting those intelligently.

At first glance it looks like scalemax and maxlim should be the same and 
equal to the spindles top speed of 24000 revs, and I'm guessing that 
minlim should be around 2400 in order to protect the spindle and vfd 
from an over-exuberance of low speed torque boosting over drive. Then 
one could S command speeds directly in rpms.

How far off am I?
 
Cheers, Gene Heskett
