Not sure a VFD will be an easy implementation?

1) Thought the Baileigh JP-1686 used a 5.5HP (4.1KW) motor? A 3HP 12A may not be enough.

2) Looking at the manual, there is a lot of extra safety switches and controls in that control cabinet as part of the jointer/planer switch over. VFD needs to be hard wired to the motor, and can’t have switches that interrupt current flow. Will need to remove the control cabinet wiring, and rewire the setup/safety switches to control the VFD, or the VFD will expel the dreaded magic smoke and stop working.

If you go VFD route, don’t rely on catalog VFD ratings. Some 3HP VFD are 10A, while others are 12A. They also have to be de-rated based on ambient temp, and cheapest units have largest de-rating factors, some starting as low as 35°C.

Best Luck.
