As per Jim's post do not use ground to obtain 120v, use the correct neutral, if switching the 120v you are permitted to switch both if desired, but if fusing is used it is only in the live conductor, never fuse the neutral.
An E-stop should break all power to motorized devices including the VFD, the controller itself can be left powered.
