With brush DC-servos and Jon's PWM amps for DC-servos I recall that
this worked very well. I will have to test with brushless when I get
my amps+motors.

Yes, and up to a point, it actually works, kinds-sorta.

My simple drives are the same way. Requiring a few percent of pwm. I
thought it was you that mentioned you could enter negative deadband into
emc (in wichita)... I have used this in testing but have not actually
tried it on a machine. I defiantly makes the dead spot at rest smaller
- if not

I've been tinkering with some brushless drives and have found something
that I'd like to improve. My brushless amps have a minimum pulse width
they will respond to. Depending on which transistors I am using, I have
different deadtime selections in the CPLD, so it goes from about 400 ns
to 1 us.
