The electronic gear function included in a servo-amplifier and a divider are used to vary the gear ratio of an electronic gear in a previously provided ratio in accordance with an external rotation position so that the electronic cam function is realized. The motor controller further includes a program execution unit so that the electronic gear is operated in accordance with programs. Since the electronic gear function and the divider is included in an inexpensive servo-amplifier and is used to realize the electronic cam function, the inexpensive and intelligent system can be realized. Since the divider is provided in the system, the number of data and the reading frequency of the cam pattern can be decreased and accordingly the inexpensive system is realized.
