Operation control device and program

A non-transitory computer readable medium which non-transitorily stores a program that causes a computer to function as an operation control device that uses a combined drive signal in which two drive signals are combined with each other to switch a drive speed of a first drive axis to drive the first drive axis, and uses one of the two drive signals to drive a second drive axis that performs another task than a task that the first drive axis performs,

• the program causing the computer to function as:
• a positional error calculation unit that calculates a positional error of the first drive axis before switching the drive speed of the first drive axis, and calculates a positional error of the second drive axis;
• a gain value calculation unit that calculates a gain value of the first drive axis after switching an operating speed, based on the drive speed of the first drive axis before switching the operating speed, the calculated positional error of the first drive axis, and the calculated positional error of the second drive axis;
• a parameter setting unit that sets the calculated gain value as a parameter of the first drive axis;
• and
• an operation control unit that uses the set parameter, the combined drive signal after switching takes place, and the one of the drive signals to be combined with each other to control operation of the first drive axis and the second drive axis.
