Not having a great deal of experience with motor controls & none with a VFD I am trying to map out a plan for two machines I have coming on line. One 3 HP Bridgeport clone, with what I assume to be a drum switch( I don't have it here yet) and one older Sheldon lathe withe a 5 HP motor & a standard reversing electromagnetic starter . Both will be wired for 230V. Both are three phase one a single phase service. From what I see A VFD would be a no brainier for both machines. Only one motor to operate on each. Looks like I can buy two VFD's that will meet my requirements for less than a good RPC.
I have searched through the forum but that only confused me some more. Basically I can wire up a standard motor starter without much problem. But the whole VFD thing is somewhat nebulous. I realize the information is probably at my fingertips, I just cannot seem to find it.
It is my understanding that the VFD is used to start the motor, not the machine controls, but the machine controls can be used to signal the VFD.
In the case of the lathe, do I simply use the buttons on the lathe control & bypass the Mag starter? and somehow wire the Fwd, rev & stop buttons into the VFD?
How does the VFD interface with the Bridgeport reversing switch? Or do I simply bypass the switch & use the VFD control panel.
I was thinking a Hitachi X200 for the Mill and Possibly A Teco 10HP 230 Volt AC Adjustable Speed Drive, Model MA7200-2010-N1. something like this for the Lathe
Am I on the right path?
Thanks,
Warren
