Motor control device

A motor control device comprising:

• a motor control unit that controls a motor;
• a signal input unit that inputs a command signal to the motor control unit;
• an input/output response calculation unit that calculates an input/output response including a gain of an input/output signal of the motor control unit from an output from the motor control unit when the command signal is inputted to the motor control unit;
• an input/output response storage unit that stores the input/output response calculated by the input/output response calculation unit;
• a condition-setting unit that sets conditions for determining whether or not characteristics of the command signal are to be changed;
• a comparison unit that compares the input/output response calculated by the input/output response calculation unit with the input/output response stored in the input/output response storage unit;
• and
• a signal-changing unit that changes the characteristics of the command signal when a result of the comparison by the comparison unit does not satisfy the conditions set by the condition-setting unit.
