<P>PROBLEM TO BE SOLVED: To provide a component mounter and a motor control method in the component mounter which can attain compatibility of both surely preventing overload state and maintaining/improving operation efficiency. <P>SOLUTION: In a motor control method of a component mounter, drive parameters 34 that regulates loaded condition of the motor to drive a head movement mechanism for moving a mounting head are individually set for each of a plurality of mounting turns as a mounting-turn specific parameter 37 corresponding to a work operation pattern of the mounting turn in such a manner that a load factor of the motor is not more than a preset reference load factor based on a rated load of the motor for each mounting turn which reciprocates the mounting head between a component supply part and a substrate. Thereby, even when workload for each of the mounting turns is greatly varied, compatibility of both surely preventing overload state and maintaining/improving operation efficiency can be attained. <P>COPYRIGHT: (C)2012,JPO&INPIT |
