During the slow start closing sequence, R2 resistance is _______.

In the context of a slow start closing sequence in elevator door operation, the resistance of R2 is at its maximum. This maximum resistance is crucial during the initial phase of closing because it helps to control the speed and ensure a smooth operation. By creating a higher resistance, the system can minimize sudden movements that might cause the doors to slam shut or operate erratically.

In a slow closing sequence, the primary goal is to enhance safety and prevent accidents by allowing the door to gently approach and close without excessive force. Thus, the maximum resistance in R2 plays a vital role in facilitating this controlled, gradual movement, providing a balance between speed and safety. Understanding the behavior of resistances such as R2 during different operational phases is essential for maintaining the efficiency and reliability of elevator systems.
