Analog Monitor Signal Settings
You can monitor the position deviation between the Servomotor and load with an analog moni-
tor.

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
).
Note: This parameter cannot be used if Pn002 is set to n.0
(Do not use external encoder).
