What does 10 mean?

An input line phase is missing, indicating a loss of one or more phases in the AC supply to the drive. This could be due to an open circuit in the supply cabling, a blown fuse, or a power distribution issue. Operating with a missing phase can damage the drive's input rectifier.

Additional Steps

Steps 1–2 are listed in Priority Fix.

  1. 3

    Physically check the supply cables connecting to the drive for any signs of damage, loose connections, or disconnections at the terminal block.
