Characterized synchronization motion control for traverser axis in spooling machine with the application of Simotion controller

Spooling machine is one important product among the catalog of IMS Deltamatic Spa. For these spooling machines, they realize the movement control of the traverser and its synchronization with other motor axis with a combination of PLC (Programmable logic control unit) and Sinamic control system, In this solution the traverser axis movement is controlled by Sinamic control unit running a DCC program, which regulates the velocity setpoints for traverser axis. However since the computational limitation of control unit, and the instinct defects of DCC when dealing with complicated motion, high accuracy of motion control for the traverser would be difficult to reach. In the thesis another solution is carried out by utilizing a new control system from Siemens named Simotion. With this new methodology, from the hardware points of view, firstly it is mounted a powerful CPU which is dedicated for complicated motion control. Moreover, it is possible to separate the logic control task for automation and the motion control task for motor axis so as to obtain high efficiency of PLC and drive. It is possible to separate the communication network so as to increase the transmission rate for motor control. On the other hand, in software aspect Simotion controller introduces OPP (Object Oriented Programming) concept into drive control, render an easy application of motion synchronization between multi axes. With all these new characteristics, Simotion is capable to improve the machine performance and spooling quality. Based on the foundation of development for the application of Simotion system in the company, multi axis control and their synchronization can be realized by the company’s standard units. I developed a unit with the functionality of inserting a spooling procedure oriented cam profile into synchronization between two axes, with an easy access to the profile parameter modification and high compatibility with standard unit.
