<...all are running parallel...>

  • Mechanically? One of the possibilities is that one of them trips on excessive mechanical load, placing that load onto the remaining three, which then trips the rest of them in cascade.
  • Electrically? Wiring. It would not be acceptable practice to run <...4...motors...> from one <...ACS800...> from a motor protection perspective.
