ABSTRACT:
In a plating apparatus 10, a known control signal for detection is supplied from a computer 50 to a motor 13 in advance; the motor 13 is rotated at a variable speed within a predetermined range; and the displacement of a basket 18 is detected by a displacement sensor 30 to obtain displacement characteristics data. Next, the computer 50 controls the rotating operation of the motor 13 through a motor controller 60 to put the basket 18 in a desired optimum state of vibration using the obtained displacement characteristics data and data of an optimum amplitude for the plating process obtained in advance.
