1.5 Selecting procedure of control mode
1.5.1 Control mode configuration
In this servo, a semi closed loop system or fully closed loop system can be selected as a control system.
Also, on the fully closed loop system, the semi closed loop control, fully closed loop control and dual feedback
control can be switched by the parameter No.PE08 settings.
