Hi Tim,
I am also a student at the University of Washington working on the same project as Matthew. We greatly appreciated your response and found it consistent with the "Motor Record and related software" documentation provided by this website: http://www.aps.anl.gov/bcda/synApps/motor/R6-9/motorRecord.html The problem we have is that the VAL field seems to change the speed of the coreless brushed motor's rotation. The YouTube video below demonstrates the speed of the motor when we set the VAL field to 100, then 30: Notice that the speed of the motor when VAL is set to 30 is noticeable slower than the speed when VAL is set to 100. Since the motor we are using is not using an encoder, the motor does not know its current position. As Matthew said earlier, VAL seems to affect the speed of the motor's rotation. I guess my question is, is there some sort of hidden relationship between the VAL field and the speed of a motor's rotation?
