:Transition commutation from close-loop to open-loop mode
Warning! This Sample Program Sets DAC output level = 1.0 Volt
Check your system's safe continuous level (i.e., check amplifier
current gain and safe motor continuous current level)
Warning! This is a sample program to assist in the integration of an
MEI motion controller with your application. It may not contain all
of the logic and safety features that your application requires.
