I finally have the Weg VFD Installed on the BP and SuperMax. It works great on both systems. On the BP, I have it connected to Mach3 (currently only ON and OFF, no speed control yet...)
Here is a picture of it installed in the old Analim 1100 CNC Control Box. I gutted it, saved the amplifies and power supply. Added pixies and a home made DB25 break out board with buffers. Also, some solid-state relays for the power supply ON/OFF connected to the charge pump, one for the auto-lub system, and one for the coolent motor too..
