PURPOSE:To flexibly meet various users demands by constituting a motor drive system to a card-like module in which an external interface section, sensor interface section, main control section, and power controlling section are separated from each other. CONSTITUTION:A main control section 47 feedback-controls the position, moving speed, and generated toque of the mover of a motor 1 based on command signals from I/Fs 41-44 and the detecting signal of an I/F 46 and outputs control signals in the form of pulse width modulated signals. A power controlling section 48 is an inverter type drive circuit which amplifies electric power in accordance with a PWM signal from the main control section 47. A total of three kinds of main power sources 491-493 are provided as the main power source 49 in accordance with the power supply voltage and output voltage. This system is constituted, at a minimum, of the external I/F section 400 composed of the I/Fs 41-44, resolver I/F 46 working as a sensor I/F, main control section 47, and power controlling section 48 and the minimum system has a module structure. |
