1. a frequency converter, comprising:

  • shell (2);

    Frequency conversion apparatus (4), it is arranged in shell (2);

    Control device (6), for control frequency conversion equipment (4);

    And user'"'"'s interface device (8), for the control command from user is sent to control device (6), it is characterized in that;

    The control device (6) of frequency converter has load audit function, between the operating period of load audit function, the potential pulse that control device (6) is configured to by producing the output of frequency conversion apparatus (4) checks whether that load is connected to the output of frequency conversion apparatus (4), described load audit function be suitable for producing when described frequency conversion apparatus (4) does not provide electric power to the output of described frequency conversion apparatus (4) the described output to frequency conversion apparatus (4) potential pulse thus, to the detection of the load being connected to frequency conversion apparatus (4) be based on to potential pulse whether in the detection of the output generation current of frequency conversion apparatus (4), control device (6) is also configured in response to being connected to frequency conversion apparatus (4), and the output frequency of frequency conversion apparatus (4) is increased to desired value by the load detected by load audit function, andControl device (6) has the multiple loadtype and control response list that prestore wherein, multiple loadtype makes it possible to from loadtype, select a type use at every turn, and control response list is for the response of often kind of loadtype determination control device (6) for the different control commands received from user'"'"'s interface device (8), namely control device (6) carrys out the mode of control frequency conversion equipment (4) in response to often kind of control command, control response list has the different content for different loads type, control response list determination control device (6) is for shutoff order, the response of the one or more orders in reverse order and step command.
