Setting to Use an External Encoder for Speed Feedback
For fully-closed loop control, you normally set a parameter to specify using the motor encoder
speed (Pn22A = n.0).
If you will use a high-resolution external encoder, set the parameter to specify using the speed
of the external encoder (Pn22A = n.1).
