10 Chapter 2 OUTLINE OF SJ-FB This manual describes the option board SJ-FB for the SJ300 series inverter. This SJ-FB board, installed in an SJ300 inverter, detects the rotation speed of a motor by accepting pulses from a shaft-mounted motor encoder, achieving highly accurate speed regulation. This SJ-FB board can also be used to c ontrol motor stop[...]
