What is the function of the Emergency stop button on the SOP?

The function of the Emergency Stop (E-Stop) button on the Standard Operating Panel (SOP) is primarily to ensure the safety of operators and equipment under critical conditions. When engaged, the E-Stop is designed to immediately disable all motion and halt operations quickly.

The correct choice pertains specifically to deactivating the servo amplifier by removing 220VAC three-phase power. This action ensures that the machinery or robotic systems powered by the servo amplifier stops functioning promptly, thus preventing potential injury or damage in an emergency situation. This immediate power disconnection is crucial in scenarios where quick action is required to mitigate risks.

The focus on the servo amplifier reflects the typical need for swift control of motion systems, which can be dangerous if left operational during an emergency. Other options, while related to emergency and operational protocols, do not encapsulate the specific and immediate function of cutting off power to the servo amplifier in response to an emergency situation.
