Anti interference wiring measures for machine tools

Technical Support:

CNC device and servo unit of NC plasma arc cutting system is the core part of the system, the power supply is the main way to enter the interference. The interference of power supply is mainly produced by the impedance coupling power supply line, all kinds of high-power electric equipment is the main source of interference.

3.1 power supply into line with shielded wire

Power line NC plasma arc cutting system. Cathode line of the cutting torch and plasma / arc arc line hanging in the sliding support, equivalent to go parallel lines tens of meters and / arc line control, torch cathode line from the plasma power, torch cathode of the DC line current 100 amperes. It produces electromagnetic field and high frequency lead arc of high frequency signal by coupling the will power of CNC device and servo unit caused by electromagnetic interference.

With copper and aluminum for shielding cable shielding layer can effectively suppress the interference of high frequency electromagnetic shielding, grounding can inhibit the change of the field of electrostatic induction core wire.

The use of 3.2 power filter

Power filter is an indispensable component in the anti interference, high frequency and low frequency section has good interference suppression performance. Use should pay attention to matters:

A) filter should be installed on the surface of the conductive metal, or woven through the ground and ground;

B) location filter should be as close as possible to the power line at the entrance;

C) filter input and output the best use of shielded wire or twisted pair;

D) to avoid the input and output lines of mutual coupling, the absolute prohibition of the input and output lines bundled with the use of shielded wire.
