This is something I'd like to see on my lathe, but no clue how to do it when the encoder is reading a 60 tooth wheel, and the response time of the vfd is so slow. I've put a mark om the spindle so that I could assemble the mt-5->er-40 stack consistently by stopping the spindle with that mark visible. For long term heat considerations, the vfd is programmed to shut down below 10 hz, but for spindle positioning much lower could be used for that short time. I'm programed also to not exceed the FLA rating of the motor for low speed boost. Is there any hope of getting a consistent stopping position on the Sheldon given the response time of the vfd for start up? Its at least 1/2 second as it starts its fans first. Or is that level of vfd control pretty much written off? As is, I have to open the door and drive the motor belt by hand if I want to find that mark. With the bronze bearings, it cannot be turned by hand unless a chuck is mounted for leverage.
