Function Block Diagram [G]; Function Block Diagram [B] - Mitsubishi Electric MELSERVO-J5 User Manual

Function block diagram [G]

The following shows a block diagram of the scale measurement function. In the scale measurement function, the control is
performed in the units of the servo motor encoder.
