VFD Wiring Diagram Explained: Main vs. Control Circuits Step-by-Step

​Master VFD wiring with this comprehensive step-by-step guide! ​In this video, we break down a Variable Frequency Drive (VFD) wiring diagram to help you understand exactly how the power supply and control signals work together to manage industrial motors. Whether you are an instrument control engineer, a technician, or a student, this guide simplifies complex diagrams into easy-to-understand sections. ​What You Will Learn: ​The Main Circuit (The "Muscle"): How three-phase power (L1, L2, L3) enters the VFD and powers the motor through terminals U, V, and W. We also cover braking units and resistors for dynamic braking. ​The Control Circuit (The "Brain"): A deep dive into Digital Inputs (DI) for start/stop commands, Analog Inputs (AI) for speed control, and Digital/Analog Outputs for status feedback. ​Communication: Understanding the RS485 port for PLC and system integration. ​Timestamps: ​[00:00] Introduction to VFD Wiring ​[00:16] Overview: Main Circuit vs. Control Circuit ​[00:36] Wiring the Main Circuit (Power & Motor) ​[01:02] Wiring the Control Circuit (Signals & Logic) ​[01:36] RS485 Communication & PLC Integration ​[01:45] Summary & Key Takeaways ​Which do you think is more critical: the main circuit or the control circuit?
