<P>PROBLEM TO BE SOLVED: To provide an electric power conversion system that automatically sets an acceleration time or deceleration time such that an electric power conversion function does not stop through overcurrent protection or overvoltage protection, and stores its setting value. <P>SOLUTION: The electric power conversion system with an overcurrent protection function of cutting off output of an inverter part when a current value detected by current detection means exceeds a predetermined value carries out acceleration or deceleration with a predetermined acceleration time or deceleration time, stops the acceleration or deceleration until an output current value or DC voltage value becomes smaller than a preset comparison value if an output current value or DC voltage value in the acceleration or deceleration exceeds the preset comparison value, and sets and stores the time from the start to the end of the acceleration or deceleration as a new acceleration time or deceleration time. <P>COPYRIGHT: (C)2012,JPO&INPIT |
