- 3. PLC training case Motor forward and reverse 2 FUZHOU FU CHANG WECON ELECTRONICS TECHNOLOGY CO., LTD. 4. Explanation In this example, the working motor is connected to the conveyor belt. The moving conveyor is required to reach a certain position. Forward button and reverse button enable the motor to rotate in both forward and reverse directions momentarily. This mode can be achieved by: giving a button input, the selected pulse output is generated, thereby driving the motor. Use the pulse function to ensure that each press of a button, only output a program scan cycle, which also means that the length of the button input time and the motor is not driven. This case uses the PLS form of the pulse command to ensure that there is a button input that immediately drives the output. Version: V1.0.0 Date: Jan 2017
