What is a TJF fault on the ATV61 and ATV71 drives?

Issue:
TJF fault on the ATV61/ATV71 drives

Product Line:
Altivar ATV61 and ATV71

Environment:
All

Cause:
TJF means IGBT overheating caused by drive overheating

Resolution:
This fault appears when the estimated temperature of an IGBT is too high.  It is a calculated measurement based on the switching frequency, drive output frequency, and motor current.
Check the size of the load, motor, and drive.
Reduce the switching frequency in menu 1.4
Wait for the motor to cool before trying to restart the drive.
