3. Product Overview

Figure 3.1: INVT GD10-0R7G-S2-B VFD Front Panel
The image displays the front panel of the INVT GD10-0R7G-S2-B VFD. It features a digital display for operational data, navigation buttons (PRG/ESC, DATA/ENT, QUICK JOG, SHIFT, UP, DOWN arrows), and dedicated RUN and STOP/RST buttons for direct control. Below the control interface, important safety warnings regarding electric shock and hot surfaces are clearly visible. The device is labeled "Goodrive10" at the bottom.
Key Features:
- V/F control mode for versatile motor speed regulation.
- Natural cooling design, suitable for environments with cotton and dust, reducing maintenance needs.
- Compact, mini structure for less installation space.
- Advanced functions including vectorization V/F control, PID function, multi-step speed control, DC braking, and Modbus communication.
4. Setup and Installation
Proper installation is critical for the safe and reliable operation of the VFD.
4.1. Mounting:
Mount the VFD in a vertical position on a flat, non-flammable surface, ensuring adequate ventilation. Maintain sufficient clearance around the unit for heat dissipation, especially given its natural cooling design.
4.2. Wiring:
Connect the input power to the designated terminals. For the GD10-0R7G-S2-B model, ensure a single-phase 230V AC power supply. Connect the motor to the output terminals. All wiring must comply with local electrical codes and standards. Use appropriate wire gauges for the rated current.
- Input Voltage: Single-phase 230V (±10%)
- Input Frequency: 50Hz or 60Hz (Allowed range: 47~63Hz)
- Output Voltage: Equal to input voltage with deviation less than 5%
- Output Frequency: 50Hz/60Hz (Fluctuation range: 5%)
Refer to the detailed wiring diagrams in the complete product manual for specific terminal connections and safety grounding instructions.
5. Operating Instructions
The VFD features an intuitive control panel for easy operation.
5.1. Control Panel Functions:
- Display: Shows operational parameters such as frequency, current, voltage, and RPM.
- PRG/ESC: Enters/exits programming mode, or cancels current operation.
- DATA/ENT: Confirms parameter settings or enters data.
- ▲ (Up) / ▼ (Down): Navigates menus, adjusts parameter values.
- QUICK JOG: Initiates a quick jog operation (specific function depends on parameter settings).
- SHIFT: Shifts cursor position during parameter editing.
- RUN: Starts the motor.
- STOP/RST: Stops the motor or resets fault conditions.
5.2. Basic Operation:
- Ensure the VFD is properly wired and powered on.
- The display will show the current operating status or default frequency.
- Press the RUN button to start the motor.
- Use the ▲ and ▼ buttons to adjust the output frequency (and thus motor speed) if configured for panel control.
- Press the STOP/RST button to stop the motor.
For advanced settings, such as PID control, multi-step speed, or Modbus communication, refer to the detailed programming section of the full INVT GD10 series manual.
6. Maintenance
Regular maintenance ensures the longevity and optimal performance of your VFD.
- Cleaning: Keep the VFD clean and free from dust and debris. Use a soft, dry cloth for cleaning. Do not use liquid cleaners.
- Ventilation: Ensure that the ventilation openings are not obstructed to allow for proper natural cooling.
- Connections: Periodically check all electrical connections for tightness. Loose connections can cause overheating and malfunction.
- Environment: Operate the VFD within its specified environmental conditions (temperature, humidity, dust level).
- Inspection: Visually inspect the unit for any signs of damage, discoloration, or unusual odors.
Always disconnect power and wait for at least 5 minutes before performing any maintenance.
7. Troubleshooting
If you encounter issues with your VFD, consider the following basic troubleshooting steps:
- No Power: Check the input power supply and all circuit breakers. Ensure connections are secure.
- Motor Not Running: Verify that the RUN command is active. Check motor wiring and ensure the motor is not overloaded.
- Overload Trip: Reduce the load on the motor. Check for mechanical issues with the motor or driven equipment. The VFD has an overload capability of 150% of rated current for 1 minute.
- Unusual Noise/Vibration: Check motor mounting, coupling, and VFD installation.
- Display Errors: If the display shows an error code, consult the comprehensive INVT GD10 series manual for specific fault code definitions and corrective actions.
If the problem persists after basic troubleshooting, contact qualified technical support. Do not attempt to repair the unit yourself.
