16.1.2 Selecting procedure of control mode
(1) Control mode configuration
In this servo, a semi closed loop system or fully closed loop system can be selected as a control system.
In addition, on the fully closed loop system, the semi closed loop control, fully closed loop control and
dual feedback control can be selected by the [Pr. PE08] settings.
