Internal structure and external wiring of the frequency converter

The internal structure and external wiring of the frequency converter are shown in Figure 1-14.
(2) Functions of each terminal
of the frequency converter     The functions of the main circuit terminals of the frequency converter are shown in Table 1-25, and the functions of the control circuit terminals are shown in Table 1-26. Due to different manufacturers
, the symbols on the inverter terminals may also be different, but the basic functions are roughly similar.
