AXIS#.SENSORLESS.ENPHASELEAD
Description
When the motor electrical frequency gets close to the bandwidth of the sensorless algorithm, the phase lag in the estimated commutation angle increases. This can increase the required voltage and current to produce the same amount of torque. A phase lead compensator is added to the sensorless algorithm to address this. This phase lead compensator eliminates the phase lag in all velocities no matter the bandwidth. Enable this feature by setting AXIS#.SENSORLESS.ENPHASELEAD to 1.
