Cause : DC under voltage comes when the DC-link voltage (DC) drops below the undervoltage limit, the drive trips after a fixed time delay. The time delay varies with unit size.

  • Check that the supply voltage matches the drive voltage.
  • Perform the input voltage test.
  • Perform the soft charge circuit test.
