Abstract
When a rotation speed is fluctuated, a fluctuation diagram showing the relationship between a fluctuation amplitude and a fluctuation period of the rotation speed is displayed on a monitor. In addition to a current setting value, a settable range of the fluctuation amplitude and the fluctuation period is displayed on the fluctuation diagram. At least one of an optimal fluctuation period Pbased on Equation (1) below and an optimal range Pof the fluctuation period based on Equation (2) below is also displayed on the fluctuation diagram, wherein T is a rotation period of a rotary shaft, and a, a, aare preset coefficients.  (1)  (2)
