Subject: Enabling axis prevents open loop BLDC movement
Tom: I finally traced back the issue with my original program. When I added the line chX->Enable = False, everthing started working.

Why would this be the case? What does enabling of an axis do to prevent WritePH3 from being able to execute properly?

Hi Erik,
 
If you enable the Axis then the Servo is constantly writing values so whatever you write will be immediately overwritten.

Ah, this is good to know. It makes sense now, but I was not aware that enabling an axis had anything to do with the Servo thread, I thought it was more of turning on a CE (chip enable) or something else "hardware-ish". Thanks for the tip.
