AXIS#.SENSORLESS.FAULTANGLE
Description
Sets the maximum commutation angle error estimated by Sensorless Field-Oriented Control (SFOC). If the error goes above this this parameter for at least AXIS#.SENSORLESS.FAULTTIME, a fault is detected. Adjust this value as needed for your application.

To find the percentage of torque loss for a given amount of commutation angle error, use the following equation:
[1 – cos(θ)] x 100 = % of torque loss
