PULSE OUTPUT IC FOR DRIVING MOTOR

摘要

PROBLEM TO BE SOLVED: To relieve burden on a CPU in electronic cam control, and to raise responsiveness in a motor for subordinate driving.

SOLUTION: A pulse output IC 20 for driving the motor comprises a cam data storage 24a for storing shape data of an electronic cam; a main spindle information management part 24b for managing the main spindle rotary angle of the electronic cam, a cam radius/motor target position calculator 24d for calculating a cam radius and a motor target position, based on cam data and main spindle information; and a motor driving pulse output 24e for outputting a motor driving pulse to perform an operation to the motor target position with respect to the motor 10B for the subordinate driving. The motor 10B for the subordinate driving is autonomously driven and controlled.
