Hey Justin, hey all,
the reason why I recommend professional brand equipment like the Omron MX2 or the Hitachi WJ200, is that they have an excellent manual that leads you from unpacking to understanding what a VFD is, over wiring and configuring a setup until you can do your first successful test run. And then, all necessary optional parts like EMI filters and brake resistors with their part numbers, and all other options in an easily understable way.
That is unfortunately not found in the manuals of cheap chinese VFDs.
I find it unreasonable and nonsensical to try out options that you search for on youtube that you don’t know the meaning of, just because the manual for the cheap Chinese VFDs is incomprehensible. I expect from a VFD to have a good, detailed and didactical manual and that I don’t have to search for anything on youtube, but that every option is introduced and explained in the manual, in a way that is easy to understand, and in my language, and in good language (not auto-translated from chinese). You find such good manuals on Omron / Hitachi VFDs as they are used in the industry. Or Invertek Optidrives.
Or you can get ready-to-use systems from spindel-shop.de. Then the VFD is already programmed to match the spindle, and it is ready to use. You also get the matching spindle cables there. It is practically plug and play including service, it is the spindle manufacturer’s shop.
