Overview

This video demonstrates how to connect and configure a WEG CFW300 inverter to control a motor using a button for direction changes and a potentiometer for speed control. It covers wiring connections and parameter programming for basic motor operation.

Key takeaways

• Wiring the Inverter: The video shows how to connect the power supply (phase/neutral for single/bifase 220V) and the motor's three phases (U, V, W).
• Connecting Control Inputs: It explains how to wire a button to terminals 1 and 5 (common) for motor direction control and a potentiometer to terminals 7, 8, and 9 for speed adjustment. Terminal 8 receives the signal, 7 is negative, and 9 provides 10 volts.
• Parameter Programming: Key parameters discussed include:
  • P100 B1: Acceleration time (set to 4 seconds).
  • P100 B2: Deceleration time (set to 5 seconds).
  • P133: Minimum speed (set to 3 Hz).
  • P134: Maximum speed (set to 70 Hz).
  • P220: Source selection for local/remote control (set to 1 for remote control via terminals).
  • P263: Input 1 function (set to 4, likely for forward).
  • P264: Input 2 function (set to 5, likely for reverse).
  • P401: Motor nominal current (set according to the motor's nameplate).
• Testing Operation: After programming, the video demonstrates how the motor's direction can be changed using the button and its speed adjusted with the potentiometer.
