The processing means (1) supposes that the reference preset velocity is vs, preset time in relation to the reference velocity vs is ts, a new preset velocity is v0, time required to reach the new preset velocity v0 is t0, and preset time in relation to the reference velocity vs at the new preset velocity of v0 is t1, the preset time t1 is calculated according to the following expression as the integrating value of rotation of an alternating-current motor coincides with the added-up value corresponding to the reference preset velocity Vs and the preset time ts, even though voluntary preset velocity v0 is set. t1=(vs/v0)<2>ts <IMAGE> |
