Is the 3ph motor on your planer running on star configuration, or wired for delta?

Is there voltage at the motor on all phases? Is the motor *totally* lifeless, or does it buzz and not run?

If you are running the VFD through a magnetic contactor, the contactor should be on the primary side.

One last point: (aplologies if you know this) a motor uses more power on start-up than any other time (inrush current) to initially move the motor (once its running, the current used will settle to a steady level). Does your VFD have sufficient reserve to cope with the start current (especially if your motor is wired for delta). Does your motor / VFD need acceleration / deceleration (ramp-up / ramp down) to run the motor up to speed?
