This sounds simple, but in a programming language, one must divide this into several steps: Start the motor with the speed equal to 90. Run the motor for 15 seconds. Stop the motor. When we make the program we do this in steps: Select the commands you need. Place them in the correct order in the block diagram. Wire the commands together. Run the program. When we make the program it is important to be aware that we are using 4 different tools: This tool is used to select various commands. This tool is used to wire the commands together.
