It can't hurt. It would give the power someplace to go in the event of an emergency shutdown.
I have a 48v, 12.5a dc supply powering a mx3660 stepper motor driver. The hardware manual for the stepper driver says to add a capacitor between the power supply and stepper driver to protect against back EMF. I have heard of people blowing out their drivers when engaging the emergency stop switch while their motors are running so I figured it would be good to follow the instructions.
Technical support from the leadshine said to use a 63v, 2200uF capacitor.
Will this really help?
Thanks!

This is a good post... Is it possible to drive back EMF if z axis slides down after shutting mill down?
A falling Z toasted my Gecko drive on my IH mill, Back EMF can do damage. Placing the cap like they said should help the PS from over reacting to a short over current event.
