Electromagnetic interference (EMI) is a common issue encountered when using advertising engraving machines. If left unresolved, it can cause malfunctions, reduce precision, and even damage the equipment. Here are some effective ways to address this problem:
First, use shielded cables to minimize external interference. These cables are designed to block electromagnetic signals from entering or escaping, ensuring that your machine operates more reliably.
Second, install a power filter to clean up the AC power supply. This helps eliminate electrical noise and voltage fluctuations that can disrupt the machine's performance.
Third, avoid signal crosstalk by carefully arranging control and power lines. For example, in a two-axis drive system, position the control and power lines in opposite directions. One line should go forward while the other goes backward. Keep these connections as short as possible to reduce the chance of interference.
Fourth, ensure proper grounding. Follow the one-point grounding principle. Connect the ground of the power filter, the drive’s PE terminal, the pulse and direction signals (PULSE- and DIR-), the motor ground cable, and the shielding of the drive and motor cables to a single grounding point on the machine chassis. A good ground connection is essential for stability and safety.
By addressing EMI with targeted solutions, you can significantly improve the performance and longevity of your engraving machine. Choosing the right equipment and following best practices will help you achieve precise and reliable results.
