Do you know how to use cooling fan in vesc correctly?

Some customer want to strengthen cooling to VESC by adding a fan, some customer may already notice that there is a feature for fan function in 75v/300A VESC poject. Only if your vesc(75v/300A project) can provide extra power supply for the fan, you can also enjoy this new feature. Then how to use it in correct way?

This blog is going to take Ubox V2 as example to show you the feature step by step.

As one of Ubox V2's unique feature, there's already 12v power circuit for fan, so there's two applications.


 Connect your fan in 12v fan port's 12v and GND pin, then the can will be on/off as Ubox v2 on/off. Here is the wiring picture.

    My vesc-tool VESC® Tool 3.01 does not have all of those additional options under the Auxilliary Output Mode. Mine just has On after X seconds.
