Cause : Communication between drive and option module (FEN-xx and/or FIO-xx) is lost.
Check that option modules are properly
connected to Slot 1 and (or) Slot 2.
Check that option modules or Slot 1/2
connectors are not damaged. To
determine whether module or connector
is damaged: Test each module
individually in Slot 1 and Slot 2
