This is a CNC spindle control panel. In my application the CNC spindle is used on a router table instead of a traditional router. The panel houses a normally open and a normally closed switch, a changeover selector and the Huanyang control panel (which is the VFD that I am using).
I would suggest using threaded inserts for the screws, makes it a really clean install.
Please note that it is dangerous to run a router in reverse on a router table! Please consider disabling this option on your VFD if using a similar application.
