7.6.6 Power Dip Ride-through
The power dip ride-through function ensures the system to run continuously at occurrence of momentary power down.
When an instantaneous power loss or a sudden power dip occurs, the AC drive compensates the DC bus voltage reduction with
the real-time energy feedback by reducing the output frequency, preventing the AC drive from stopping due to undervoltage.
