Technical Manual for EA350 Analog Pulse Type Servo Driver V101 Chapter 9 Applications of fully closed loop 9.1 Preparations 1. Please purchase the EA350 series servo driver that comes with the fully closed-loop feature (which is not included in standard products). 2. Please also purchse our fully closed-loop module E18-PG-1 separately to form a system as shown below. Caution ☞ The figure above is a connection diagram for the external encoder. For connection details on power supply and peripherals, please refer to Chapter 3. Mechanical wobble or twisted connection will result in unstable positioning precision or vibration of the fully closed- loop system. 3.
Set the basic parameters properly for the servo driver, and toggle it to position control mode. 4. Servo gain adjustment: With the fully closed-loop function not enabled, check if the basic settings for the master and the servo are correct, and if the connections of mechanical components are proper, and perform identification of load-inertia ratio. 9.2 Box diagram of fully closed-loop control 236
