green
Warning
The bus voltage dropped 150V
below the bus tracker voltage.
Monitor the incoming AC line for low voltage or line
power interruption.
Refer to the Understanding Precharge and Ridethrough
Faults section for more information.

Bus Cycle>5 CP, Solid
green
Warning
At least 5 ridethrough cycles
have occurred within a 20 second
period. This indicates a converter
problem or a problem with the
incoming power.
Monitor the incoming AC line for low voltage or line
power interruption.
Refer to the Understanding Precharge and Ridethrough
Faults section for more information.
If you do not want this condition to be reported as a
warning, change bit 4 in Warning Select 1
(parameter 21) to 0.
