I3 Fault Q Full Resettable
Fault Coast The fault queue is full. There are at least three other faults in the queue.
Troubleshooting and clearing the existing faults will make room for
additional faults in the queue (if any).
This fault may occur during a normal power down sequence.

I2 Incompat PS
I3 Incompat PS Resettable
Fault Coast The drive has detected an incompatible power supply for the drive AC
input rating.
• Check the power supply and replace it if incorrect.
• If the power supply is correct, re-flash the control board.
• If this problem persists, replace the inverter power supply board or
power layer interface board.

10334 I1 UBrd Fault
I2 UBrd Fault
I3 UBrd Fault Resettable
Fault Coast The power supply on the U, V, or W phase gate driver board has failed.
• If this fault occurred on this phase only, replace the appropriate gate
driver board.
• If this fault occurred on all three phases, check the 24V power supply
on the inverter power supply board that feeds the gate driver boards
and replace the inverter power supply board if necessary.

I3 Cur Offset U Alarm 1 The current sensor for the U, V, or W phase is not reading zero (off by
more than 1% of the inverter rated current), while the drive is not
running.
• Check the current sensor’s offset reading inverter testpoint and
power supply. If necessary, replace the current sensor.
• If this problem persists, replace the inverter power supply board and/
or the power layer interface board.
