After receiving the VFD I decided to test it on the bench before assembly in its final location. I connected everything as it should and powered up the VFD. Each time I tried to run the spindle...

For some reason you are hung up on using the default 50HZ/60Hz settings. Whatever gave you that idea?

The L510 gives an option of seven different V/F curves. The first six are fixed curves for...

I have decided to stay with the TECO Westinghouse L510 VFD. The reason is simply that there is nothing wrong with this drive. After a long conversation with a factory tech, it became apparent that...

I'm not as inclined to let the TECO Westinghouse guys off the hook as you are. They are putting out a product that is designed to drive high RPM, 400 Hz motors. I may be inclined to give the techs...

Hi Mactec54

Tonight I am a very happy camper! I was able to conrol The VFD using the RMSV3.1 controller for both ON/OFF and spindle speed. However I plan to control the spindle speed using a pot...

Some good news (hopefully). I got both of my motors to spool up to 400 Hz last night while I was fooling around with the V/F curve settings. Tech support from TECO Westinghouse leaves a lot to be...

The original VFD did run the motors but it would not communicate with my controller so I gave it to a friend where it now drives the motor for his auto Koi feeder. Who the hell knows what the model...

Hi Mactec54

I am still going back and forth with TECO Westinghouse, but the prospects are not looking too promising. Here is the latest from them:

"the L510 is a micro not really intended for...

Here us the last piece of the puzzle (hopefully). The clamp on current readings on both line and neutral input wires are 2.4 amps. This only lasts for about 3 seconds, then the drive shuts down due...

Took both of my spindle motors to a very reputable electric motor repair shop where they were meggered and found to be in good condition with no faults indicated. Does that let the spindle motors...

OK, first I want to make sure that we are on the same wavelength with respect to what the motor is doing. When I press RUN on the keypad the motor starts up and runs for approximately 3 seconds. ...

After a couple of phone discussions with the factory I learned that this VFD has 6 fixed V/F curves (three for 50 Hz and three for 60 Hz) The seventh curve is user configurable for 400 Hz. But in...

Grounding the case should not affect whether or not the motor will run. This is mainly to protect me or some other unsuspecting person from touching the case or CNC frame in the event one of the...

Hello mactec

Yes I did run the spindle motor with the original VFD. It seemed to work quite well. The main problem is that it would not communicate with my controller and I had to start-stop and...

Dear Mactec

I really appreciate that you have taken the time to assist me with my VFD issues. I have gone through all the parameters that you have listed and programmed in your suggested values. ...

Attached is the user manual for the L510

I am in the process of building a small CNC router for woodworking, at least I was in the process. This whole spindle motor debacle has put a screeching halt to my projects.

I originally purchased...
