5.9 Full closed-loop input
The full closed-loop system is a system which is installed on the moving machine by the external
position detection device (such as encoder, grating ruler, etc.) to detect the position of the control object
and feedback the machine position information to the servo unit in real time. The full closed-loop
control mode can ensure that the external machinery has no deviation and improve the control accuracy.
At present, the full closed-loop function supports all control modes.

When the full closed-loop is opened, the external grating ruler position feedback is used; when the
full closed-loop speed feedback is opened, the external grating ruler speed feedback is used. When the
full closed-loop mode is on, the control mode can be switched (P0-01 and P0-02).
