Motor Starter Instruction Example

The Motor_Starter Add-On Instruction starts and stops a motor.

If the stop pushbutton is closed and the start pushbutton is pressed then:

· the motor gets the command to run.
· the instruction seals in the command, so the motor keeps running even after you release the start pushbutton.

If the stop pushbutton is pressed (opened), then the motor stops.
