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.
