Application Notes: If line loss is set to ‘‘U Volt Run” and [Run On Power Up] is enabled, the drive will run as long as the bus
voltage is high enough to maintain logic.
To obtain longer power ride-thru, choose “U Volt Run”. This allows the output power to be on from time T
1
to T
3
. To obtain a
longer control ride–thru, choose “F03 Enable”. The output power devices are turned off at time T
5
but note that time T

– T

is
greater than time T
