10.3.9 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 Direct Drive Servomotor and a high-resolution external encoder, set the param-
eter to specify using the speed of the external encoder (Pn22A = n.1).
Parameter
Pn22A
Note: This parameter cannot be used if Pn002 is set to n.0 (Do not use external encoder).
