Abstract

Based on the requirement of dynamic strength in free-wheeling toys at the toy safety standard, we designed and developed the practical automatic dynamic strength tester. The tester, taking Siemens S7-224 PLC to control the motion of Minas A4 Series AC Servo Actuator, uses Pulse Train Output generator issued variable frequency high-speed pulse to control Servo Actuator, applies internal high-speed Counter to receive and count the feedback signal coding of Servo Actuator and applies Pulse Width Modulation generator to realize speed synchronization following function. Using this tester can not only be realized as the automatic test of dynamic strength in free-wheeling toys and greatly improved the precision of the test but also can enhance the level of whole system’s automation.
