Hi
generally autophasing is a function that, depending on the FW of the drive, serves to improve the calibration of the best performance of the drive in that specific application.
I don't have the FW manual of your Firmware type, but the description of the function in the std manual is quite intuitive:
"Autophasing is an automatic measurement routine to determine the angular position
of the magnetic flux of a permanent magnet synchronous motor or the magnetic axis
of a synchronous reluctance motor. The motor control requires the absolute position
of the rotor flux in order to control motor torque accurately"
So it is a specific function that the drive can activate, under certain operating conditions, which adapt the parameters - for example the gain - to get the best performance from your drive.
Hope this help you
