6. Maintenance

The Walfront HF020-7X1T1M module is designed for durability and requires minimal maintenance. Adhering to these guidelines will ensure its longevity and reliable performance.

• Cleaning: Keep the module clean and free from dust and debris. Use a soft, dry cloth for cleaning. Avoid using liquid cleaners or solvents.
• Environmental Conditions: Operate the module within the specified temperature range of -5℃ to 60℃ and in a non-condensing environment. Protect it from excessive moisture, direct sunlight, and corrosive substances.
• Connection Checks: Periodically inspect all wiring connections to ensure they are secure and free from corrosion or damage.
• Firmware Updates: Check the manufacturer's website for any available firmware updates. Follow the provided instructions carefully if performing an update.

7. Troubleshooting

This section provides guidance for common issues you might encounter with the HF020-7X1T1M module.

7.1 Controller Version Viewing Method

To view the controller's version number:

1. Press and hold the ENT (OK) key.
2. While holding ENT, power on the module.
3. The version number will be displayed on the screen, for example, [21.100].

• The first two digits (e.g., 21) indicate the year (e.g., 2021).
• The next two digits (e.g., 10) indicate the month (e.g., October).
• The last digit (e.g., 0) indicates the version without RS485 communication, while 8 indicates a version with RS485 communication.

7.2 Common Issues

• No Power: Check the DC 12-24V power supply connection and ensure correct polarity. Verify the power source is active.
• Motor Not Moving: Verify motor driver connections (PUL, DIR), power to the motor driver, and motor wiring. Check if the RUN command has been issued and if parameters are set correctly.
• Incorrect Movement: Review the direction and step parameters. Ensure the motor driver is configured correctly for the stepper motor.
• Display Errors: If the display shows unusual characters or no information, try restarting the module. If the issue persists, contact support.
