In a servo-type weighing system, the analog signal from the weighing controller fluctuates.
At Company B's factory, which manufactures plastic products, there is an automatic weighing machine for resin raw material pellets that are transported by a conveyor belt. This system controls the gate opening detected by a device that outputs an analog signal from a potentiometer, inputs it into a PLC, and sends a signal to the servo driver for control. While operating this system, a problem occurred where the gate opened and closed in small increments, making accurate weighing impossible. If this continues, it will have a significant impact on product production... This case was related to "high-frequency noise propagating through the air." *For more details, please refer to the PDF document or feel free to contact us.*
