Chapter 2 OUTLINE OF SJ-FB
This manual describes the application board SJ-FB for a SJ300 series inverter.
This SJ-FB board, assembled in a SJ300 inverter, detected the rotation speed of a motor with the
encoder and feedback the motor speed to suppress speed fluctuations for highly accurate operation.
This SJ-FB board can also be used for controlling motor stop positions by entering 90 phase
difference pulses, as well as for synchronized operation, orientation function, and external torque
limit input function. Figure 2-1 Function Block Diagram
