HDM VFD reported rpm vs asked

If you can get the password to unlock the VFD, you should be able to manually set the spindle speed with the potentiometer on the VFD. Do you do a lot of speed changing?

Is it repeatable?


My VFD isn’t locked. When my spinderella died I changed p3 and p4 and had speed control with the pot…


Awesome! How does that work? I.E. What are the spindle speeds at the minimum and maximum pot settings? Can you please correct/augment the attachment with your VFD parameters?

Good to know, more learning for me.
