X DBSE1Online 544 The drive detected that the diagnostic feedback from this
SGCT device on the DB side did not match the gating pattern.
After isolating the drive from MV, ensure that the device,
IGDPS power supply and the fiber-optic signals are not
damaged.
• Complete a resistance check per the instructions in the manual.
• NOTE: SGCTs may not have completely shorted, and still could read in the k range – Any
devices with low suspect readings should be changed.
• Check the LED status of the SGCT gate driver card for abnormal readings.
• Complete a Gating Test mode check on the devices.
• Verify the associated 20V power supply is powered and active.
• Verify all the power connections to the SGCT firing card are seated properly.
• For nuisance faults, contact the factory about extending the Diagnostic Delay.

X DB Airflow Fault 570 The drive has detected that either the DB exhaust
temperature or the DB ambient temperature has exceeded
the corresponding trip level. For the DB Airflow Fault the drive
has detected that the airflow in the DB cabinet is below the
trip level.
• Verify the trip and warning settings match the factory recommended values.
• Check TFB, temperature sensors and airflow sensor in DB cabinet.
• Verify that feedback values are consistent with actual conditions.
• Ensure that ambient conditions do not exceed specifications.

X DB Airflow Sensor 573 DB airflow sensor not functioning. A warning is issued if this
happens while running and a fault is issued when the drive is
stopped.
• Check TFB and airflow sensor in the DB cabinet.
• Verify that feedback value is consistent with actual conditions.
X DB AmbientSensor 572 DB temperature sensor not functioning. For DB Resis Sensor, a
warning is issued if this happens while running and a fault is
issued when the drive is stopped.
• Check TFB (onboard ambient sensor) and DB exhaust temperature sensor in the DB
cabinet.
• Verify that feedback values are consistent with actual conditions.
X DB Resis Sensor 571
X DB fiber-optic 574 DB TFB is not functioning. • Check TFB in the DB cabinet.
• Verify that feedback values are consistent with actual conditions.
X DBR Overload 575 Braking energy dissipated in DB Resistor exceeded the fault
threshold (i.e. 150% of DBR rated energy). This is a calculated
measurement and does not reflect any physical feedback.
• Verify DBR parameter settings are correct.
• Verify DC Current feedback measurement is correct.
X DC Link Flow Low
(C-Frame Only)
72 The flow switch in the DC Link coolant path has detected the
flow is less than optimal, indicating a problem with the flow
path. This is not designed to specifically measure flow. This is
a switch that differentiates between flow and no flow.
• Verify pressure values in the cooling system are nominal.
• Verify the cooling path is not restricted because of tube crimping.
• Check flow switch for proper operation.
• It may be required to disconnect cooling path and complete a check on the DC Link for
blockages.
