Single Phase Overload

What does 33 mean?

This fault occurs when the drive is configured for single-phase operation (parameter 517), and the DC bus voltage ripple exceeds the drive's allowable limits. This indicates the input power demand is too high for the drive's capacity in single-phase mode. This can lead to drive instability and potential damage if overloaded.
