Overvoltage

What does 2 mean?

The DC-link voltage has exceeded its defined limits. This typically occurs due to an excessively short deceleration time, where regenerative energy from the motor causes the DC bus to rise, or high overvoltage spikes in the supply voltage. Persistent overvoltage can damage the frequency converter's internal components.

Additional Steps

Steps 1–2 are listed in Priority Fix.

1. 3

   Activate the overvoltage controller function.

2. 4

   Check the input supply voltage for spikes or instability.
