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 -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
