Is Back EMF Safe for Victors?
When a motor is backdriven, it becomes a generator and creates a voltage across its input terminals. This is called Back EMF, and the voltage produced is proportional to the angular velocity of the output shaft.

Does anyone know if creating this Back EMF will damage a powered Victor speed controller? And if so, what is the max amount of current that can be "backdriven" into a Victor without damaging the electical components?

In laymens terms... Can I set a Victor to coast mode, hook up a CIM motor to it, turn the bot on, backdrive it at 5000 RPM and live to tell about it?
