Abstract
In coping with the trend toward the much higher powered electric-motor driven injection molding machine, multi-AC servomotors control system has become necessary in order to control the molding machine mechanism. Thus, it is inevitable to use the synchronous position control technology not to cause the excessive mechanical stress in the machine body. Accordingly, it is much necessary to have a load simulator of the molding machine to study the control technology. This paper clarifies the similarity law between the actual molding machine and the simulator so that we are able to anticipathe the control performance at the actual machine from that at the simulator.
