Struggling to Synchronise VFDs? Delta + Danfoss AO/AI Fix
Learn how to synchronize two Delta VFDs using analog output (AO) and analog input (AI) in this practical industrial automation tutorial. This video explains Delta VFD synchronization, also known as master-slave VFD control, where one drive sends a speed reference signal to another drive.
This method is widely used in motor speed synchronization, conveyor systems, pump control, and other industrial automation applications — all without using a PLC.
In this video, you will learn:
1.Delta VFD AO to AI control setup
2.How to configure analog signal (0–10V / 4–20mA)
3.Wiring connection for VFD master slave control
4.Parameter setup for Delta drive frequency reference
5.How to achieve accurate motor speed tracking
6.Troubleshooting VFD synchronization issues
This is a simple and cost-effective solution for synchronizing two motors using VFD, ideal for technicians, electricians, and engineers working in automation and control systems.
