Electromagnetic interference (EMI) is a common issue encountered when using advertising engraving machines. If left unchecked, it can cause malfunctions, reduce precision, and even damage sensitive components. So, how can we effectively address this problem? Here are some practical solutions:
First, use shielded cables to minimize external interference. Shielded cables act as a barrier, preventing unwanted electromagnetic signals from affecting the internal circuitry of your engraving machine.
Second, install a power filter to clean up the AC power supply. Power filters help eliminate electrical noise and voltage fluctuations, ensuring a stable and clean power source for your machine.
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 on opposite sides of the machine. One line can be routed forward while the other is routed backward, and ensure that all wiring is kept as short as possible to reduce interference.
Fourth, ensure proper grounding. Follow the one-point grounding principle: connect the ground of the power filter, the drive’s PE, the pulse signal PULSE-, and the direction signal DIR- to a single grounding point. Also, make sure the motor's ground cable, the drive’s cable shielding, and the drive’s shielded wire are all connected to the chassis grounding column.
By addressing EMI with targeted solutions, you can significantly improve the performance and reliability of your engraving machine.
