VFD Tagalog | Inverter

Introduction

In this tutorial, we will explore how to use a Variable Frequency Drive (VFD), also known as an inverter, to operate a 3-phase motor using a single-phase power supply. This guide will cover the key settings and features of the XSY-AT1 model inverter, including ramp up and ramp down functions, and how to easily change the direction of the motor without needing a magnetic contactor.

Step 1: Understand the VFD and Its Features

Before diving into the setup, familiarize yourself with the essential features of the VFD:

• Ramp Up and Ramp Down: Controls the acceleration and deceleration of the motor to prevent mechanical stress.
• Jog Function: Allows for precise forward and reverse motion.
• Frequency Control: Adjusts the motor speed by changing the frequency of the power supply.

Step 2: Set Up the VFD

Follow these steps to properly set up your VFD:

1. Connect the VFD to Power Supply:

   • Ensure the VFD is rated for single-phase input if using a single-phase supply.
   • Connect the VFD output to the 3-phase motor.

2. Download the Manual:

   • Access the inverter manual for detailed specifications and guidelines: Inverter Manual.

3. Access the Control Panel:

   • Power on the VFD and navigate to the control panel.

Step 3: Configure Key Settings

Adjust the following settings on the VFD to optimize performance:

1. Maximum Operating Frequency (P06):

   • Set the maximum frequency for the motor operation.
   • Example: If your motor is rated for 60 Hz, set P06 to 60.

2. Main Rising Velocity (P34):

   • Determine how quickly the motor reaches the set frequency.
   • Example: A value of 5 seconds is common for gradual acceleration.

3. Main Descent Velocity (P42):

   • Set the deceleration time for the motor.
   • Example: Also set to 5 seconds to match the acceleration.

4. Jog Forward Frequency (P86):

   • Define the frequency for forward jogging.
   • Example: Set to a lower frequency for precise movement.

5. Jog Reverse Frequency (P87):

   • Set the frequency for reverse jogging.
   • Example: Similar to the forward jog frequency.

6. Jog Rising Velocity (P88):

   • Adjust the acceleration time for jogging forward.
   • Example: 2 seconds for quick response.

7. Jog Descent Velocity (P89):

   • Define the deceleration time during jogging.
   • Example: Set to 2 seconds for uniform control.

Step 4: Test the Motor

After configuration, it's time to test the motor:

1. Start the Motor:

   • Use the start button on the VFD to initiate motor operation.

2. Observe Performance:

   • Watch for smooth acceleration and deceleration as per your settings.
   • Check if the motor can easily switch from forward to reverse.

3. Adjust Settings if Necessary:

   • If the motor does not perform as expected, revisit the configured settings.

Conclusion

You have successfully learned how to set up and configure a VFD to control a 3-phase motor using a single-phase supply. Key takeaways include understanding the importance of ramp functions and frequency settings, as well as how to utilize the jog feature for precise motor control. For further exploration, consider experimenting with different settings and monitoring their impact on motor performance.
