In this video, we introduce and explain the automatic web detect signal feature of the SCU6x Controller. This functionality ensures that the actuator stops moving when the web breaks, even in automatic mode. The video illustrates how the actuator guides the web back and forth and demonstrates the lock on lost edge feature, which holds the actuator's position if no web is detected. This feature is crucial for preventing disruptions in operations when re-threading the web. Join us as we dive deep into how this innovative feature works and its benefits for maintaining smooth operations.
