Should i use the sleep or enable pin?

Hey guys,
I am using big easy drivers to power my stepper motors and i want to be able to turn the drivers on and off so tehy dont get hot when im not using them. At the moment i have wired the power source via a switch but i have just noticed the "Enable" and "Sleep" pins on the drivers. Can i control these via the arduino so that the drivers are turned on when i tell them to? (Kinda like a programmed switch)
