Abstract:
    The invention discloses a seamless inserted variable-frequency speed regulating system, characterized in that it comprises central controller, A/D converter, D/A converter, interface circuits, and branching circuit, where the central controller is connected through two buses with the A/D converter and D/A converter, respectively, the A/D converter is connected with n interface circuits which are connected with n independent sensors; the D/A converter is connected with m branching circuits, each of which is externally conencted with two inverter control ends; two ports are connected with a variable-frequency speed regulating system, and ports A and B are inveter control singal input ends. And it has characters of not changing original control functions and forms of the system, and only providing intelligent/energy saving service after connection; ability to connect simultaneously with two or more variable-frequency speed regulating circuits, and implementing their respective intelligent/ energy saving controlled operations; and the operating interface is brief and convenient.
