What must be engaged before pressing ENTER for INSERT, MODIFY or DELETE in motion step programming?

In motion step programming, engaging SERVO power before executing operations like INSERT, MODIFY, or DELETE is essential because these adjustments often involve controlling machinery or robotic components that rely on servo motors for precise movement.

When SERVO power is enabled, the system is prepared to make the necessary real-time adjustments to the motor's position or behavior as commanded by the programming changes being made. Without activating the SERVO power, the commands would not take effect since the motors would remain inactive, which means the intended programming changes would not be executed.

This requirement emphasizes the importance of safely managing power to mechanical systems, ensuring that all movements can be accurately controlled and monitored as programming changes are implemented. Engaging the SERVO power allows for the proper integration of programming commands with actual motion mechanics, critical for successful motion programming and execution.
