In this video, we explore an important feature of the SCU6x Controller related to the servo center position. We discuss a scenario where operators are not permitted to change the servo center position and how the controller can be configured to lock this setting. By clicking on the motor icon, operators will only be able to see the jog left and jog button options, while the reset servo center button will be hidden. This feature ensures that operators can view the actuator position without being able to reset the servo center, thereby facilitating manual movement of the actuator for loading and unloading rolls. Additionally, we highlight the automatic web guiding capability of the system to its desired position.
