1. Install a power filter to reduce the interference of the AC power supply to the equipment.
2. "One point grounded" principle. Ground of the power filter, the driver PE (ground) (insulated between the driver and the chassis base), the control pulse PULSE- and the direction pulse DIR- shorted lead wire, the motor ground wire, the cable guard between the driver and the motor, and the driver The shielded wires are connected to the grounding posts on the wall of the chassis and require good contact.
3. Try to increase the spacing between the control line and the power cable (L, N) and the motor drive line to avoid crossover. For example, when we deal with the two-axis drive system where two drives are located in a unified chassis, a drive name plate is The other one is facing backwards and makes the leads as short as possible in the structural arrangement.
4. Use shielded cables to reduce outside interference with yourself or yourself (power cord) to the outside world.
After the above process, the system works reliably.
