The allowed level of imbalance in input current entered as x.x%.
An Input I Imbalance fault (fault 225) is generated if Line I Imbalance (22) is
greater than I Imbalance Limit (62) for this amount of time.
If Ride Through Ena (64) is set to Disabled, then any interruption in input
power or AC line synchronization causes an immediate AC Line Lost fault
(fault 227).
If Ride Through Ena (64) is set to Enabled, then any interruption in input power
or AC line synchronization causes the rectifier to enter its standby state and start
its ride through timer. If the ride through timer expires before the input/
synchronization loss ends, the Ride Thru Abort fault (fault 221) occurs. If the
input power/synchronization loss ends before the ride through timer expires, the
rectifier leaves Standby and re-enters its normal running state.
The ride through timer of the rectifier expires when it reaches the value in Ride
Through Sec (65).
Note that the ride through timer of the rectifier is independent of the power loss
timer of the inverter, and that the inverter generally enters its power loss state and
starts its power loss timer as soon as the rectifier enters the Standby state and
starts its ride through timer.
