Abstract
A plural motor changeover control system for using a plurality of motors (1a, 1b), the power outputs of which differ, by successively switching among the motors. A conversion table (32a, 32b) corresponding to a motor designated for operation from among the plurality of motors (1a, 1b) is selected, and an amplitude command is fetched from the selected conversion table, which command corresponds to a velocity error, which is a difference between an actual velocity of the designated motor and a commanded velocity. The amplitude command is applied to the servo control circuit to control the designated motor.
