<P>PROBLEM TO BE SOLVED: To relieve burden on a CPU in electronic cam control, to raise responsivity in a motor for subordinate driving, and to dispense with an encoder and a motor for driving a main shaft, which is arranged only for rotation to operate the motor for subordinate driving. <P>SOLUTION: A motor driving pulse output IC 20 and the electronic cam control system 1 autonomously control the driving of an electronic cam subordinate control circuit 24 by fetching a pulse signal for driving the motor of the virtual main shaft as main shaft information. The electronic cam subordinate control circuit 24 includes a cam data storage part 24a for storing shape data of an electronic cam; a main shaft information managing part 24b for managing the main shaft rotation angle of the electronic came; a cam radius/motor target position calculating part 24d for calculating a cam radius and a motor target position, based on cam data and the main shaft information; and a motor driving pulse output part 24e for outputting the pulse for driving the motor to a subordinate driving motor 10 to be operated to the motor target position. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
