10 HP VFD - $172.00 with free shipping. As I previously stated, I have been using the 5 HP version for several years with no complaints.
If the piece of equipment in question has input terminals for the three 3 phase power, and all the other single phase accessories are wired internally (as I would expect - since all of my large cnc machining centers separate the 3 phase and single phase components internally) - then the only wiring to be done is to connect the three output wires of the VFD (plus ground wire) to the three input terminals (plus ground terminal) of the equipment. Since this application is for phase conversion only and not speed control, the VFD programming for ramp up, ramp down, torque control, decelerating stop, coasting stop, DC braking, etc. would not necessarily apply. This should be a pretty straight forward installation. It would also be nice to see the installation manual, wiring diagrams, and other specs for the piece of equipment in question. This could help make a more informed decision.
