Component mounter drive system
With respect to servo amplifiers attached to a component mounter, a motor unit of at of a drive mechanism assembled on a mounting head is attached to be exchangeable. A control device of the component mounter switches the servo amplifier from a servo on state to a servo off state before exchange of the motor unit, maintains servo amplifier system power in an on state, initializes an encoder of the motor unit connected to the servo amplifier after the motor unit has been exchanged, and returns the servo amplifier to a servo on state. By this, the servo motor of the exchange motor unit achieves a state in which feedback control can be performed based on detection information of the encoder, and operation of the exchanged motor unit can be started.
