2x72 belt sander/grinder (diy) : heat and belt wobble

[bbaley]

Mine has near zero vibration. I credit that mostly to the motor running very smooth.

For spin up/down, the VFD likely has long ramp times set by default. You can likely turn them way down. I've got mine set to 5 seconds. I think the default was 30 seconds. If you go too fast, it will throw errors on the VFD.

I do have the ramp set about that - 5+ seconds, don't remember exactly.

I alos found some settings for this particular VFD that were the cause of significant "wobble" early in the project, for which the MFG had specific settings.
