    Have you tried starting the motor across the line (bypassing the VFD) to confirm that the motor is good?
    Verified the wiring to the motor?
    Does the drive display an error code?

      Sounds like it is being given a run command with a speed reference of zero.

        Did amything change, or did this just start happening all of a sudden? Is there a disconnect switch between the drive and the motor that might be open?

        I'm in California, ergo I am still stuck on the 2014 NEC... We'll get around to the 2017 code in around 2021.

          Green for run? I'm used to red for run, green for off. Are you sure it's getting a run input?

            With limited information, so far that sounds like best possibility.

              How are the RUN and SPEED commands being sent to the VFD ? Hard wired digital inputs or over network ?

                1336F by the way is an old ALLEN BRADLEY drive, not ABB (Asea Brown Boveri).
                1336F drives were discontinued in 1998, Rockwell had a "last buy" on components for repairing them in back in 2006, and they were officially made obsolete, meaning no more support for them, in 2014. 16 years is a long time for continued support on anything electronic like that, longer than most, but all good things must come to an end some day. Might be time to think about upgrading them to never versions.
