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.

Complete Troubleshooting Guide

1. 1

   Extend deceleration ramps to allow for a more gradual energy dissipation during braking.

2. 2

   Check the supply cable connection to the braking resistor to ensure it is secure and functional.

3. 3

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

4. 4

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