Proposal for position and speed control of parallel motors by implementing PAC and HMI in a gantry-type crane
Abstract
Engineering creates and employs a large amount of machinery and instruments helping humans to perform tasks with some ease; an example of that are cranes, which enable to move loads of huge weights without the necessity of human force. Parallel motors control is considered a favourable strategy to implement in cranes, for example at port industry, due to the complexity of this type of systems. This work constitutes a terminal academic project of practical application, focused on the industrial-type processes automation, in which a proposal for position and speed control of alternating current parallel motors is stated in order to actuate a gantry-type crane, by using automation technologies such as a GE Fanuc PAC System RX3i, whose programming is accomplished by means of LD language through the software Proficy Machine Edition; an HMI, developed using the software Cimplicity Workbench; and the communication protocol MODBUS, for communication between motors and variable frequency drives for speed control.
