摘要： PROBLEM TO BE SOLVED: To provide a power converter which can judge the factor of overheating when a fault occurs. SOLUTION: The power converter comprises modular main elements 1 and 3 in a power semiconductor 13, a temperature detection circuit 11 for detecting overheat temperature of the power semiconductor, and a fan 6 for cooling the power semiconductor 13 by supplying air to a cooling fin 10 mounting the power semiconductor 13. The power converter supplies AC power of variable voltage variable frequency to an AC motor and indicates fault when the AC motor is faulty. The power converter is further provided with a circuit for detecting the number of revolutions of the cooling fan 6, and indicates fault such that the factor of temperature overheat can be judged using an overheat detection signal outputted from the temperature detection circuit 11 and a number of revolutions signal outputted from the number of revolutions detection circuit.

摘要： PROBLEM TO BE SOLVED: To provide an inverter arrangement wherein the user can easily change and restore set values with respect to initial value data groups. SOLUTION: An area 3 for storing initial value data groups specific to primary users and an area 4 for storing initial value data groups specific to secondary users are formed outside a parameter storing area 2. Thus, data can be replaced and saved between the parameter storing area and an parameter temporarily storing area 7 as required. As a result, even if it is necessary for a customer of a user product with the inverter arrangement built in it to modify the contents of an initial value data group, the user can carry out modification by him/herself without asking the manufacturer of the inverter arrangement. Thus, the manufacturing process oriented to the user can be reduced. COPYRIGHT: (C)2004,JPO
