Although stepper motors have anti-interference characteristics, we often encounter problems with stepper motors interfering with other equipment, affecting the normal operation of the equipment, so how should we solve them?
1. Power filter can be installed to reduce the pollution of AC power.
2. One-point grounding. Ground the power supply filter, driver, control pulse and pulse direction-shorting lead, motor ground wire, and cable protection sleeve between driver and motor, and the driver shield wire is connected to the ground pole on the chassis wall and requires good contact.
3. stepper motor wire can increase the anti-interference magnetic ring to reduce the motor interference to the outside world.
4. The distance between the control line and the power supply line and motor drive line as large as possible to avoid crossing. For example, when we deal with two drive mounting positions in the same chassis in a dual-axis drive system, one drive nameplate face forward and the other face backward, and make these leads as short as possible in the structural arrangement.
5. Use shielded wires to reduce interference from the outside world to yourself or your own power lines to the outside world.
6. Signal isolation, using metal plates to isolate equipment or strengthen the equipment of the source of interference.
When you encounter interference with stepper motor equipment, I believe the above methods can help you solve the trouble, so that interference problems do not occur again!
