PLC-based Frequency-conversion Speed Control System for Three-phase Asynchronous Motors
In this paper,a frequency-conversion speed regulation system for three-phase asynchronous motors was de-signed based on Siemens S7-315 PLC and Siemens S120 drive system.The design entails supplement and improvement of the previous study and addressing the applicative environmental limitations of DSP,so as to result in improved utility in frequency-conversion speed regulation of three-phase asynchronous motors.
