Description of strong current interference of peripherals

What kind of influence does strong electric interference have on the numerical control encircle word opportunity?

First of all, let's understand the essential reason of strong electric interference. Inductive loads such as relays, contactors and electromagnets in the circuit of numerical control encircling machine will produce reverse voltage or impulse current when waiting for power failure, which will form interference signals. These interference signals will affect the drive circuit itself, but also cause interference to the external interface, which will disturb the execution of the NC encircling machine program.
