Braking with regenerative feedback to the line

Overview
The typical applications for braking with energy recovery (regenerative feedback into the line
supply) are as follows:
• Hoist drives
• Centrifuges
• Unwinders
For these applications, the motor must brake for longer periods of time.
The converter can feed back up to 100% of its rated power into the line supply (referred to "High
Overload" base load).
