In a servo-based 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 inputs the analog signal output from a device that detects the gate's opening degree via a potentiometer into a PLC for control, and sends signals to a 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 significantly impact product production... This case was related to "high-frequency noise propagating through the air." *For more details, please refer to the PDF materials or feel free to contact us.*
