A motor controller contains three selector push buttons labeled 'start', 'jog', and 'stop'. What will happen to the motor when the 'jog' button is depressed?

Awill run continuously after the 'jog' button is released
Bwill not stop unless the 'stop' button is pushed
Cwill not start until both the 'jog' and 'start' buttons are pushed
Dwill run until the 'jog' button is released
AI Explanation

The correct answer is D) the motor will run until the 'jog' button is released. The 'jog' function on a motor controller is typically used to manually move the motor a short distance or at a slow speed, often for setup or maintenance purposes. When the 'jog' button is pressed, the motor will run, but only as long as the button is held down. Once the button is released, the motor will stop. This allows the operator to precisely control the motor's movement without it running continuously. The other answer options are incorrect because: A) the motor should not run continuously after the 'jog' button is released, B) the motor should stop when the 'jog' button is released, not require the 'stop' button, and C) the 'jog' button alone should be sufficient to start the motor's jogging operation without also needing to press the 'start' button.
