The VFD has had intermittent problem with starting up and times turning off when in use. The front key panel has been replaced, it worked okay for some time but same issue came back. The VFD is on a POWERMATIC WOOD LATHE. The front led readout will have OFF flashing and no other key pad function. I have checked E-STOP switch, switch for motor direction and speed dial .all checked out. Please let me know if this is a unit you can service.
