      Does F1 occur while traveling a constant speed, or when a certain speed is reached?

      If yes, perform the following recommended steps:

      1. If the fault occurs while the motor is running at a constant speed then the load on the hook may be swinging. Increasing the acceleration and deceleration times may also help reduce the swinging which may be causing motor problems.
      2. If the fault occurs when a certain speed (in Hz) is reached, verify that the drive is hooked up to the correct windings on your motor (e.g. make sure if you have a 460V motor that you are not hooked up to the 230V windings).
      3. Verify that your motor is a 60Hz motor. If it is a 120 Hz motor (or some other frequency), contact PE® for assistance with setting the output parameters correctly.
