PROBLEM TO BE SOLVED: To provide a motor controller, whose set values can be easily and surely restored to the original state, when a control board is replaced. SOLUTION: This motor controller regulates the speed or the output torque of a motor by changing at least one of the voltage, current, and frequency, which are supplied to the motor via a power converter. To this end the controller has a control board, in which memory means which can store and update a set of set values necessary for the control of the power converter and a changing means, which changes the set values of the memory means, are incorporated in common. The memory means, incorporated in the control board, includes first and second memory means in which respective set values are simultaneously stored and updated, and at least either of which is detachable. |
