Richard,
You can change the abnormal Kt detection window by changing Abnormal Kt lock detect threshold.
if abnormal Kt is getting fired at low RPM, please increase the open loop to close loop treshold.
If you see abnormal KT is getting fired at middle or high RPM, you can check what KT value devcie is calculating from display tab and make change into your motor parameter.
If you can't solve the issue with one of two options above. You might have disable abnormal Kt for your application.
Thanks,
Seil
