VFD setup: Brook Crompton motor, Teco vfd

You can get the metric Lesson motor, they work fine for this application and less expensive then the BC motor. Manufacturer Part Number: 192205.00 which is a 3 phase 1710 RPM motor. These come with a 24.0mm shaft, so not sure what your pulley size is, but may have to bore one. You can run a single belt, you do not need dual belts. The alternative is to adapt a US frame motor like the Marathon E467 which is a US 145 frame size and very compact since it is a TENV motor. Follow the links and look at the dimension drawings.

Mark, thank you buddy. IIRC the pulley bore should be 24mm but I'll measure it. I'm at work now and getting busy so I'll have to check into things tomorrow. Thanks.
 
I have a few minutes to search while at work. Looks like a 145T should closely match a 90L. I may have to enlarge the mounting holes in the 145T motor mount and get a single 7/8" bore pulley roughly 2.25" diameter for a 4L Fenner twist type belt.
 
OK. I decided on the Leeson 192205 and Hitachi WJ200-015SF since it seems to be popular. Gonna be a metric drop-in so should be good to go. I'm used to my Teco vfd I have on another machine but I'm sure I can figure most of the features out on the Hitachi. Now the fun begins of figuring wiring. Shouldn't be too bad but the spindle fwd/rev/stop switch on the carriage might be a PITA. Don't know if I need the 24v psu. Off the top of my head I guess if I wanted to use lighted E-stop and power buttons I'd have to. Also, I have to check wiring for the motor. Time to start studying up. I'd like to keep this as simple as possible.

The Hitachi WJ200 is a good VFD. It is worth reading the manual. FYI, when this unit is powered up, the default is for Hz = 0. This means if you hit "START" nothing happens. You need to get to the parameter for Hz and change this for e.g., 30 Hz.

The WJ200 can be programmed from a laptop, which is much faster than going through the keypad.
 
Thanks Dave. Wow, the s/w is available for d/l from Hitachi. Sweet!
 
Weird. Getting an error when extracting the files. I tried multiple d/l from Hitachi's site and keep getting error. Looks like the zip file is corrupted per 7zip. Interesting. I googled the file and found another spot on Hitachi's US site where you have to register to d/l the s/w, which is nowhere said on the first page I found it at. Once you register and d/l it it seems to work fine.

Mark (MKSJ), I'm going to use your schematic and parts list for my G4003G. The wiring appears easier than I thought it would be, but you've done the homework first. I thank you wholeheartedly for sharing your efforts and knowledge with everyone. I've started reading the manual this morning and know the basic parameters that need changing but has anyone put together a chart or cheatsheet of settings on the WJ200 that should be changed? Thank you.

The WJ200 would need a slightly different schematic, I can put together something as to a schematic and parameters depending on the motor and VFD you end up with. A few WJ200 parameters to change. The WJ200 needs both a JOG command and a JOG direction so requires a second normally open switch block for the JOG switch which connects to the FORWARD input. The VFD terminals are also labeled differently. The WJ200 also needs an external braking resistor for use on the lathe, usually 50-75 ohm, 300-500W.

Ah, I see. Not as simple as I hoped, but that's ok. I ordered the Leeson 192205.00 motor and Hitachi WJ200-015SF drive. I started to rip the contactors and transformer from the G4003G circuit box tonight. Believe it or not I think I'll actually prefer the more straightforward wiring of the VFD! As for the brake, I just ordered this one tonight and I think it'll handle the job. The halogen light on the lathe burnt out months ago so I'm using a seperate 110v LED lamp going to wall outlet. That's it. I'm done for tonight. Got a lot done though. Thanks Mark.
