I just acquired an excello mill and am trying to wire it up. I have a Chinese vfd 2.2kw. I have it wired and it works fine controlling the mill from the vfd itself. I am now trying to wire the drum switch to start/stop and fwd/reverse. here is a pic of the diagram for the vfd
I found two circuits on the drum switch with one common between them. I hooked the common up to ground (black wire) and the other 2 red wires to fwd, and rev on the vfd. When I switch the drum switch it tries to start and just bumps the mill motor ahead a little at a time. Now I am realizing that I may have only hooked up the controls for fwd/rev and not start/stop but I cant find them on the vfd circuit. I did program it to receive the command source from external control, I just am not sure I am actually hooked up to it right. Any ideas?
