Delta VFD & 3-Phase Motor Wiring Diagram ⚙️

Components and Connections:
3P MCCB 400V 3-Phase:
This is a 3-phase Molded Case Circuit Breaker, providing overcurrent protection for the entire system.
Three Phase Line Choke, 440V:
Two line chokes are shown, likely used for smoothing the input current to the VFD and reducing harmonics.
Variable Frequency Drive (VFD):
The central control unit, regulating the speed and torque of the 3-phase motor.
Power Input: Connected from the line chokes (R, S, T) to the VFD's power input terminals.
Motor Output: Connected from the VFD's motor output terminals (U, V, W) to the 3-phase motor.
Control Inputs:
Open Push Button & Close Push Button: These buttons are wired to the VFD's digital inputs (MI1 and MI3) and a common ground (DCM) to control motor start and stop.
Potentiometers: Connected to the VFD's analog input (ACM) and +10V, providing a variable voltage signal to control the motor's speed.
3-Phase Motor:
The motor is connected to the VFD's output terminals.
