Star-Delta Starter PLC Program and Wiring – Part 4

Overview

This video continues the Star-Delta Starter PLC Program and Wiring series, focusing on the motor winding terminals and real-world wiring connections.

It explains how the six motor terminals (U1, V1, W1 and U2, V2, W2) are arranged and how they are accessed in actual motors.

The video shows how to properly connect these terminals to form star and delta configurations, which are essential for implementing a star-delta starter system.

Understanding terminal connections is critical for correct wiring, safe operation, and successful implementation of motor control systems in industrial environments.
