That would be your opinion not mine I always attatch and use the braking resistors with a VFD for spindle use.
Money WELL spent in my opinion.

Ditto. Cant be waiting around for spindles to stop. Time is money. Parts need to go out the door, and I don't want to spend any more time in the shop than what I have to. A breaking resistor cost what..less than $15. I'll take that any day of the week. Lets see how this breaks down, and I'm being conservative for my machine use....10 seconds X 100 = 16.6min per day X 5 = 83 min per wk. One 5 day week is bad enough, let alone months or a year. That's not just lost time either, its lost production as well. Your right, some people on here do give bad, costly advise. Good thing we have great people like Terry (BR549) that freely give their vast knowledge to the masses.
 Thank you Terry.

I use this one on my Hitachi. Works like charm. I only use it for the fwd/rev function though. I prefer to manually control the spindle speed with a potentiometer, and that is wired directly to the VFD, if I remember correctly. A couple things to keep in mind when getting a VFD is to make sure it can use modbus, if you intend to have modbus. Not all of them can. You might want a breaking resistor to stop the spindle too. Some VFD's require an additional piece of hardware in order to connect the resistors. The additional hardware can cost as much as the drive itself. The hitachi sj200 (probably other models too) does not require any additional equipment (other than the resistors) and is modbus capable. There's allot of bang for your buck, and I suppose that's why they have a large following.

No problem at all, happy to help. That's what were here for. Just glad that's what it was, otherwise I was out of ideas.

Yes, as long as that is where your notepad location is. Click "browse" to make sure it is indeed there. If not, browse to its location and select.

And.....make sure the delay is set long enough to accompany the ramp up/down.

Only thing that I can think of right off hand would be to check your editor location in the toolbar menu ...... Config>General Config. Make sure the location for the editor is valid.

Not saving the options that you have set, sounds like there might be a file permission set to read only. Would be a nice and easy fix if that's all it is.

For you? I'll make a trade. Motor prints for space.  :D Wouldn't do me much good though, as the list of things I want/need to make is to long already.

Sweet! Nice to see you back, Steve.
