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!
