Overvoltage in mains

What does F2815 mean?

The input mains voltage has risen above the permissible overvoltage threshold. This indicates an issue with the electrical supply, potentially damaging the drive's input rectifiers, DC bus capacitors, or other sensitive components. Overvoltage can lead to immediate drive shutdown to prevent hardware damage.

• Power grid voltage surge or spike
• Incorrect mains voltage selected or supplied to the drive
• Malfunctioning voltage regulator in the power supply
• Faulty mains filter or surge protection device
• Incorrectly set overvoltage threshold parameter

1. 1

   Verify actual incoming mains supply voltage at the drive input terminals (L1, L2, L3) against the drive's nominal input voltage specification.

2. 2

   Inspect all input power wiring, including main contactor, fuses, circuit breaker, and terminal connections, for looseness, corrosion, or signs of overheating.

3. 3

   Check the drive's configuration parameters for nominal input voltage (e.g., P0201 for IndraDrive) and overvoltage threshold settings to ensure they are correctly matched to the installed power supply.

4. 4

   Monitor the mains supply voltage over a period using a power quality analyzer to detect intermittent voltage swells or transient overvoltage conditions from the grid.
