Undervoltage

What does F030 mean?

The Undervoltage fault occurs when the line supply voltage to the drive is too low or experiences a transient dip. This can lead to unstable drive operation or shutdown to protect internal components.

• Input line supply voltage is below the specified operating range for the drive.
• A transient voltage dip occurred on the power supply line.
• Loose or corroded power connections to the drive's input terminals.

Click steps to track your progress.

1. 1

   Check the incoming line supply voltage at the drive's input terminals and compare it to the drive's nominal voltage.

2. 2

   Inspect all power connections to the drive for proper termination and tightness.

3. 3

   Review the Undervoltage menu (607-) parameters (page 106), especially Undervoltage detected fault management (607.0) and Undervoltage prevention (607.1), to ensure appropriate settings for the application.

4. 4

   Monitor the line voltage for transient dips using a power quality analyzer.
