摘要

PROBLEM TO BE SOLVED: To reduce power consumption with respect to a current control method of a stepping motor.;SOLUTION: In a period from a time t2 when the driving state of the stepping motor M is transited to a constant speed state from an acceleration state to a time t3, a current amount in the acceleration state immediately before the constant speed state is continuously fed to the stepping motor M during an overtime Ta1 that corresponds to the driving state from overtime data stored in overtime data 241a. A current amount fed in a period from the time t3 when the constant speed state is stabilized to a time t4 is set on the basis of the maximum torque D in the period from the time t3 to the time t4.;COPYRIGHT: (C)2005,JPO&NCIPI
