Cause : Acceptance test/confirmation pending - This fault occurs after a startup clone. It can also be caused by a faulty read from the EEPROM, see F51 for more details.

  • A startup clone could have changed and might not match the application.
  • This parameter set needs to be checked before the inverter can start a motor.
  • r0949 = 3/4: Inverter data change
  • r0949 = 5: Startup clone via an MMC/SD card has been performed
  • r0949 = 10: Previous startup clone was aborted.

The current parameter set needs to be checked and confirmed by clearing the fault.
