repeatability, density and uniformity of the coating.
Magnetron sputtering coating equipment mainly uses DC magnetron sputtering, which often requires two channels of stable DC power supply. After setting a voltage value, it is required to quickly respond to the set value of voltage. The power supply must be stable during use, and the voltage value cannot be affected by the load. However, the commonly used switching power supply in the market is open-loop control, which cannot ensure stable output, and a stable voltage is very important to the coating quality. Therefore, it is envisaged to use the existing DC switching power supply through the PID algorithm of PLC to realize the rapid regulation and closed-loop management of the power supply. In the intelligent power supply control system, 4ai is needed to detect the current signal and voltage signal of two DC regulated power supplies as the feedback signal of the intelligent power supply; It is necessary to use 2ao to control the voltage output, so that the power supply has good load characteristics and maintains constant voltage output.
Based on the above requirements, PLC selects the s20m0t switch and analog mixed host of Haiwei. The host is equipped with 4 channels of AI analog linear input and 2 channels of Ao analog linear output. The analog quantity supports
