8.3 Parameter Settings for Fully-closed Loop Control
8-23
8
Fully-closed Loop Control
8.3.7 Analog Monitor Signal
The position error between servomotor and load can be monitored with the analog monitor.
8.3.8 Speed Feedback Method during Fully-closed Loop Control
Use Pn22A.3 to select the speed feedback method during fully-closed loop control: Normally, set Pn22A.3 to
0 (Uses motor encoder speed.).
Note: This parameter cannot be used when Pn002.3 is set to 0.
