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

The current passed through the regenerative braking circuit is computed from this set resistance value, and a loss produced in the power semiconductor in the regenerative braking circuit at this current value is determined. The allowable duty factor of the power semiconductor is determined from this loss produced. COPYRIGHT: (C)2009,JPO&INPIT
