Undervoltage in mains

What does F2814 mean?

The input mains voltage has dropped below the permissible undervoltage threshold. This indicates a problem with the electrical supply to the drive, which can lead to insufficient power for the internal circuitry and the power stage. Prolonged undervoltage can cause erratic behavior, reduced performance, or damage to components.

• Power grid sag or brownout condition
• Undersized power supply cabling to the drive
• Loose connections in the mains power circuit
• Faulty mains contactor or circuit breaker
• Incorrectly set undervoltage threshold parameter

Click steps to track your progress.

1. 1

   Measure the incoming mains voltage at the X1 power input terminals of the IndraDrive MPx02, comparing it against the drive's specified nominal voltage and acceptable tolerance.

2. 2

   Inspect all upstream power supply components, including circuit breakers, contactors, fuses, and associated wiring, for proper sizing, signs of damage, or loose connections.

3. 3

   Verify the mains voltage monitoring parameters within the IndraDrive's configuration to ensure they are correctly set for the installed power supply.

4. 4

   Check for intermittent voltage sags or instability in the facility power supply using a logging multimeter or power quality analyzer, especially if the fault occurs sporadically.
