PURPOSE:To provide a method for preventing a vibration servomotor at the starting time. CONSTITUTION:When a servomotor is driven for starting from a stopping state to a full speed, a current deviation value between a current instruction value 1 and a current feed back value 2 is multiplied by a current gain 3, and the resulting value 4 is distinguished by a circuit 5 whether this value is over a previously set ceiling value or not. If the value 4 is over, this value is limited to the ceiling value and multiplied by a current gain 8, which is under unity in a following step, to generate a current output value 9. If the value is not over, the value 4 is multiplied normally by a current gain 7 at a following step to generate the current output value 9. In this way, in a servo motor can be prevented at the starting state. |
