47. Ball Mill Motor Control Introduction to Allen
In the previous section, we configured the timer T4:1 to time for 20 seconds after the Ball Mill motor starts. If the motor stops for any reason, we will need to determine if the motor has run for the 20second time period. A TON timer is reset when the input logic to the timer is false, so if the motor stops, I will lose the accumulated time and the Done bit if it is has been set.
