PWM RECTIFIER SGCT WARNING
This warning occurs if Redn Dvc Rec option
is selected in HardwareOptions1 (P141).
This SGCT device on the rectifier side was
detected to be faulted after the input
contactor was closed or following a start
command or following a drive reset. 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 kΩ
range – Any devices with low suspect
readings should be changed
– Check the LED status of the SCGT 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
SCGT firing card are seated properly
– NOTE: There is only the Redundant
option available on the Rectifier, and
only on 6P drives (SCR orPWM). You
can not have N-1 operation on the
rectifier since we can not control the line
voltage.

PWM RECTIFIER SGCT WARNING
This warning occurs if Redn Dvc Rec option
is selected in HardwareOptions1 (P141).
This SGCT device in the rectifier section
was detected to be faulted while the drive
was running. The drive detected that the
diagnostic feedback from this device 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 kΩ
range – Any devices with low suspect
readings should be changed
– Check the LED status of the SCGT 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
SCGT firing card are seated properly
– Reset the drive and let the offline
diagnostics further define the problem
– For nuisance faults, contact the factory
about extending the Diagnostic Delay
– NOTE: There is only the Redundant
option available on the Rectifier, and
only on 6P drives (SCR orPWM). You
can not have N-1 operation on the
rectifier since we can not control the line
voltage.
