Chapter 2 Warning Messages
X X X SyncXfer Failure 145 A synchronous transfer was not completed in the time specified
in Synchronous Transfer Time (P230). This warning will occur if
the sync transfer fault is masked, and the drive will continue to
run at the last reference command before a synchronization
command was initiated.
• There is instability at synchronous speed. Check for stability of the
synchronous transfer process/speed regulator.
• The motor cannot reach synchronous speed due to a heavy load.
• Check the load conditions for torque limit or low alpha line (low line
voltage).
• Consult the factory for review of synchronous transfer parameters.
• This fault indicates that the drive failed to synchronize the motor to
the bypass within the specified time. Adjust the Sync Reg Gain
(P225), Sync Error Max (P228), Spd Reg Bandwidth (P81) for a
smooth transfer.
X X X X X X T DC Link High 67 Indicates that the Autotune T DCLnk (P218) measured was
greater than 0.100 seconds, and the T DC Link (P115) will have
to be tuned manually.
• Refer to the Commissioning chapter in the PowerFlex 7000 Medium
Voltage AC Drives User Manual for autotune procedures, results and
actions.
X X X X X X T DC Link Low 66 Indicates that the Autotune T DCLnk (P218) measured was less
than 0.020 seconds, and the T DC Link (P115) will have to be
tuned manually.
X X X X X X T Rotor Low 72 Indicates that the Autotune T rotor (P222) measured was less
than 0.2 seconds, and T rotor (P132) will have to be tuned
manually.
X X X X X X T Rotor High 73 Indicates that the Autotune T rotor (P222) measured was
greater than 5.0 seconds, and T rotor (P132) will have to be
tuned manually
X X TempFeedbackLoss
(C-Frame Only)
42 While running, the drive has detected a missing temperature
feedback. A missing sensor can be interpreted as either 0°C
(32 °F) or over 100°C (212 °F) and both are unrealistic values.
• Verify that the sensor is completely seated properly on the TFB.
• Measure the sensor resistance and replace if necessary.
• NOTE: This is a warning because the drive should not fault on the
loss of the signal while running. There is no imminent danger to the
drive, but the user needs to be aware that there is a temperature
feedback signal missing.
X X TFB FbkData Err 407 The drive has lost the fiber-optic signal from the specified
temperature feedback board.
• Check for a damaged fiber-optic cable or loose connection.
Tuning Abort 58 Autotuning could not be completed in two minutes or had to be
aborted due to drive stop/fault.
• Check the alarm queue and perform manual tuning if problem
persists.
• Investigate why the Autotune test aborted, and retry the Autotune
test.
• Verify that the autotune default parameters are sufficient to
complete the test.
• Make sure that the speed min/max and ramp time are set to the
default values.
• Also, refer to the tuning section in user manual.
• Attempt to manually tune the drive.
UPS Battery Low 115 Warning that the UPS battery is low. • Replace the UPS battery.
