Selecting Procedure Of Control Mode; Control Mode Configuration; Dual Feedback Filter Equivalent Block Diagram - Mitsubishi Electric MR-J3-B-RJ006 Instruction Manual

1. FUNCTIONS AND CONFIGURATION

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.
