6.12 Ride Through Function
The Ride Through function enables the system to run continuously during short time
power failure.
When a power failure occurs, inverter keeps in the Regenerative status, the DC Bus
Voltage is maintained in FE.16
，
avoid inverter stop due to short time input voltage cut off
to cause Undervoltage Fault.
