Abstract
The crane operates in three directions, hoisting, traversing, and travelling motion. In this study, an AC drive system for these motions of the crane is developed and tested. The command from an operator is transmitted to PLC, which sends data to a main controller by fieldbus protocols such as Profibus or Devicenet. And the main controller is connected to other auxiliary ones by CAN bus. The each controller, which has the same structure, regulates its motor speed from the operator's command.
