1. A control device for performing synchronization control over a master axis and a slave axis to follow an electronic cam profile, the control device comprising:
a reference position calculator configured to, in response to power being restored after a power disconnect, obtain a position of the master axis and calculate a reference position of the master axis and a reference position of the slave axis based on the obtained position of the master axis, a position of the master axis at cam synchronization, and the electronic cam profile; and
a return control unit configured to perform return control to determine a position of the slave axis corresponding to a current position of the master axis based on the current position of the master axis, the electronic cam profile, and the reference position of the master axis and the reference position of the slave axis calculated by the reference position calculator, and to move the slave axis to the determined position.
