How to solve the following interference problems when the woodworking engraving machine encounters the following problems?

Today, Superstar CNC will share with you how to solve the following interference problems encountered by the woodworking engraving machine:

The machine suddenly fails to work normally, and the mechanical and electrical parts have been tested, but no reason can be found? Are you having this kind of problem? Superstar CNC engraving machine manufacturers have summed up a few experiences, hoping to help everyone.

On the 1325 woodworking engraving machine, because the general stepping motor and driver casing are not magnetically shielded by aluminum, titanium, and magnesium alloy casings, it will interfere with the highly sensitive receiver system woodworking engraving machine, making it unable to work, and pollute the power supply, causing control. The single-chip microcomputer and the host computer of the system cannot communicate, and in severe cases, the single-chip computer crashes, which makes it difficult for normal use.Therefore, the interference problem must be solved.

The following measures can be taken to solve:

A.Install a power filter to reduce the pollution to the AC power supply.

B. "One point ground" principle. Connect the ground of the power filter, the ground(the driver is insulated from the woodworking engraving machine board at the bottom of the chassis), the control pulse PULSE- and the direction pulse DIR-the lead wire after short-circuiting the woodworking engraving machine, the motor ground wire, the driver and the motor The cable protective sleeve and the shielded wire of the driver are all connected to the grounding column on the chassis wall, and good contact is required.

C. Try to increase the distance between the control wire and the power wire (L, N) and the motor drive wire (U, V, W of the woodworking engraving machine) to avoid crossing. For example, when we are dealing with the installation positions of two drives in the same chassis in a dual-axis drive system, one drive nameplate is facing forward, the other is facing back, and these leads are as short as possible in the structural arrangement.

D. Use shielded wires to reduce the interference of the outside world to yourself, or the interference of yourself (power woodworking engraving machine wire) to the outside world.

After the above treatment, the interference problem of the engraving machine can be effectively solved.
