Implementación de un módulo de simulación de puente grúa comandado por relés programables y variadores de frecuencia.

Abstract

A bridge crane module was implemented that simulates transverse, longitudinal and vertical movements with three-phase motors, which are controlled by a programable relay and a frequency inverter, taking into account that students can have a module to complement the knowledge theoretical in the matter of automation and electrical control with the practical part. It is necessary to perform the modeling of the movements performed by the bridge crane simulation module for its construction, then the functional scheme of the control and power circuits is made, this circuits provides us with the necessary information for the acquisition of electrical elements and selection of the control panel, it uses to assemble and install the control panel, it must position properly the elements inside the board tray to preserve its aesthetics and its maintainability. The appropriate color code must be considered for the electrical connections for its correct identification. The configuration of the frequency inverter is carried out manually, taking into account the technical characteristics of the motors. For the programming of the control system we use the software LOGO Soft Comfort V8.0, this is done taking in to account which are the inputs and outputs of the programmable relay for the development of a control circuit, this control circuit must be transformed into Ladder diagram, it is entered into the LOGO by an Ethernet cable. The final result will be a module that simulates the movements of the bridge crane, these movements are one at a time with the activation of the motor that is intended for that movement, this application can be implemented can be implemented in the industrial field. It is concluded that the implementation of this system reduces construction and maintenance costs. And it is recommended to use the operation manual and follow the laboratory guide to operate the module.
