摘要：
When a fact that a motor cannot rotate at a target speed in a stationary state is detected by a speed controller (rotation control means, detecting means), this fact is alarmed to the operator. The rotational speed of the motor is switched to a different speed and the other drivers are also driven in accordance with the switched speed.
