A power conversion device includes an AC conversion unit; a detector that detects an output current, a DC voltage, and a temperature; an I/O unit; and a control unit. The control unit includes a motor control unit that controls the AC conversion unit; an operation instruction/parameter setting unit that converts an operation instruction and a parameter; an information management unit; an I/O control unit; and a detection unit that acquires data of the detector. The operation instruction/parameter setting unit outputs the set parameter and characteristic data to the information management unit, which acquires parameter information associated with the operation instruction and parameter information for an operation instruction change quantity required for adjustment from an information server. The operation instruction/parameter setting unit converts the operation instruction into a parameter using the data acquired by the detection unit and the parameter information and sets the parameter in the motor control unit.
A power conversion device comprising:
A parameter setting method of a power conversion device including an AC conversion unit that converts a DC voltage to a desired AC voltage, a motor control unit that controls the AC conversion unit, and a detector that detects an output current of the AC conversion unit, the DC voltage, and a temperature of the AC conversion unit, the power conversion device further including an information management unit that manages parameter information associated with the operation instruction and parameter information for data detected by the detector, a set parameter, and characteristic data, the parameter setting method comprising
A motor control system having a power conversion device that controls a motor,
