Abstract

The development of industrial automation systems requires electric motor control that is efficient, reliable, and easy to operate. One of the methods used to regulate the speed of an induction motor is by utilizing a Variable Speed Drive (VSD) controlled by a Programmable Logic Controller (PLC). This study aims to design and develop a three-phase induction motor speed control system based on a Schneider Modicon TM221CE16R PLC, Human-Machine Interface (HMI), and Schneider ATV320U15M3C VSD using a three-stage multi-step method. The system was designed with three operating frequency levels, namely 15 Hz, 35 Hz, and 50 Hz. Motor speed measurements were carried out using a tachometer as a reference for the RPM value. At frequencies of 15 Hz, 35 Hz, and 50 Hz, the motor speeds obtained were approximately 450 rpm, 1044 rpm, and 1490 rpm, respectively. These results indicate that the motor speed is directly proportional to the VSD output frequency and closely matches the theoretical values, with minor deviations caused by induction motor slip. Furthermore, the HMI successfully functioned as an effective operation and monitoring interface, demonstrated stable performance, satisfactory accuracy, and ease of operation, making it suitable for educational purposes and industrial automation control applications.
