Abstract

PURPOSE:To reduce the vibration of a wire and the driven body, by a method wherein start-up is made gentle by decreasing the amplification degree of the difference between the velocity feedback signal and the velocity instruction signal only during a given period in the starting of a DC motor. CONSTITUTION:When the start pulse arrives, a velocity-setting unit VPU closes a switch SS3 corresponding to the velocity designating code. On the other hand, a mono-stable multivibrator MB is triggered by the start pulse. In response thereto, a relay coil L is energized. Consequently, the amplification degree of an operational amplifier OP to amplify the difference between the velocity instruction signal and the velocity feedback signal becomes small, so that a motor M starts gently. When the rotational velocity of the motor M has risen to a certain extent, the output of the mono-stable multivibrator MB is inverted to deenergize the relay coil L. Consequently, the amplification degree of the operational amplifier OP becomes large, so that the motor M rotates at the designated speed.
