DC link overvoltage

What does 07 mean?

The DC link voltage has exceeded its permissible maximum limit, often caused by excessive regenerative power generated during braking, or potentially a ground fault. This triggers an immediate switch-off to protect the inverter's sensitive electronic components from damage.

Additional Steps

Steps 1–2 are listed in Priority Fix.

1. 3

   Verify the technical data and functionality of the braking resistor to ensure it can absorb regenerative energy.

2. 4

   Thoroughly check for any ground faults within the system that could contribute to overvoltage conditions.
