Spindle VFD compatibility

Post by Ozyrob »

Hi, I'm looking to upgrade my spindle motor to an 11kw AC servo. I've attached the controller that comes with the motor. Just wondering if this will be compatible with the Allin1DC and if the encoder can be used for rigid tapping, or do I need to stick with the external one I've fitted. It will be belted 1:1 with a timing belt.

You should be able to make it work.

It appears that it will accept run-forward, run-reverse and reset inputs; accept a 0-10V analog speed command; and provide a contact-closure fault output.

It also appears that its encoder output is a suitable differential signal.
