Core Features & Market Positioning

The INVT GD10-2R2G-2-B distinguishes itself through its robust sensorless vector control, providing superior torque performance and accurate speed regulation even under fluctuating loads. This capability is crucial for applications where consistent airflow is paramount, setting it apart from basic V/f-only drives. The integrated braking unit offers enhanced stopping power, contributing to system safety and operational flexibility. Positioned as a high-value, performance-driven solution, the GD10-2R2G-2-B targets small to medium-sized enterprises seeking reliable, energy-efficient fan control without the complexity or cost of higher-end industrial drives. Its intuitive design and straightforward parameter settings also contribute to its competitive edge in ease of use.

Key Application Scenarios

This VFD is exceptionally well-suited for a wide array of small industrial fan applications. It excels in HVAC systems for precise air volume control in commercial buildings, ensuring optimal comfort and energy efficiency. In manufacturing, it's employed for exhaust and ventilation fans in workshops, reducing airborne contaminants and improving working conditions. The GD10-2R2G-2-B also finds application in material handling systems, controlling fan speeds for dust collection and pneumatic conveying processes. Its adaptability makes it a go-to choice for poultry farm ventilation, greenhouse climate control, and any scenario requiring variable speed for centrifugal or axial fans.

Practical System Integration Guidance

Integrating the INVT GD10-2R2G-2-B into existing fan systems is streamlined due to its compact design and accessible terminals. Ensure a stable, grounded power supply matching the 230V single-phase input. For motor connections, utilize three-phase wiring to the motor terminals for optimal performance. Wiring for control signals, such as start/stop commands or speed reference inputs (analog or digital), should follow the clear diagrams provided in the user manual. Parameter configuration is critical; key settings include motor F-parameters (rated voltage, current, frequency, poles), acceleration/deceleration times, and the desired control mode (V/f or sensorless vector). For basic fan control, setting the maximum frequency and V/f curve is often sufficient to achieve significant energy savings.

Operation and Risk Mitigation

Operating the GD10-2R2G-2-B VFD requires adherence to safety protocols. Always ensure the unit is de-energized before making any wiring changes. During operation, monitor motor temperature and VFD status via the built-in display or optional communication interface. Common troubleshooting involves checking for overload faults (often due to incorrect motor parameterization or undersized motor) or overvoltage faults (typically related to regenerative energy in braking applications or line voltage fluctuations). Error code E.01 typically indicates an overload condition, while E.03 might signal an overvoltage issue. Proper ventilation of the VFD is essential to prevent overheating, which can lead to premature failure.

Scalability & Long-Term Value

While the GD10-2R2G-2-B is designed for small fan applications, its underlying INVT technology platform offers a degree of scalability. Its compatibility with standard communication protocols like RS485 (with optional module) allows for integration into basic SCADA or PLC systems, facilitating remote monitoring and control. This enables users to incorporate fan speed management into broader automation strategies. The long-term value is significantly enhanced by the energy savings achieved through precise speed control, directly reducing operational costs. Furthermore, the drive's ability to soft-start and soft-stop motors minimizes mechanical wear, extending the lifespan of connected fan equipment and reducing maintenance expenditures.

Frequently Asked Questions

Q1: How do I connect a three-phase motor to the INVT GD10-2R2G-2-B VFD?

The GD10-2R2G-2-B, while operating on single-phase input, outputs a three-phase power supply to the motor. Connect the motor's three power leads (typically labeled U, V, W or T1, T2, T3) to the corresponding output terminals (e.g., T1, T2, T3) on the VFD. Ensure all connections are secure and properly insulated. Always consult the VFD's wiring diagram in the user manual for precise terminal assignments.

Q2: What are the primary benefits of using the INVT GD10-2R2G-2-B for industrial fans?

The primary benefit is significant energy savings, as fans only consume the power required for the specific speed setpoint. It also provides precise speed control, leading to improved process stability and consistent airflow. Reduced mechanical stress on the motor and fan assembly, due to soft-start and soft-stop capabilities, extends equipment lifespan.

Q3: Can this VFD be used for applications requiring reverse rotation?

Yes, the GD10-2R2G-2-B supports reverse rotation. This is typically achieved by swapping any two of the three motor output phases (U, V, W) in the wiring. Alternatively, parameter settings within the VFD may allow for directional control without altering the physical wiring.

Q4: What is the maximum motor power rating compatible with the GD10-2R2G-2-B?

The INVT GD10-2R2G-2-B VFD is rated for a 2.2kW (3 horsepower) motor. It is crucial not to exceed this motor power rating to prevent VFD damage and ensure safe operation. Always verify the motor's nameplate data against the VFD's specifications.

Q5: How do I set up the basic V/f control for a fan application?

To configure basic V/f control, you'll need to set parameters like the motor's rated voltage, frequency, and current. The maximum output frequency and acceleration/deceleration times are also key settings. Access these via the VFD's keypad interface and adjust them according to your fan's operational requirements.

Q6: What does the IP20 rating signify for this VFD?

An IP20 rating indicates that the VFD is protected against solid objects greater than 12.5mm in diameter (like a finger) and has no protection against water ingress. This means it's suitable for clean, dry indoor environments and must be protected from dust, moisture, or corrosive elements.

Q7: Is it possible to remotely control the speed of the fan connected to this VFD?

Yes, remote speed control is achievable. The GD10-2R2G-2-B can accept speed reference signals from external sources, such as a potentiometer or a 0-10V DC / 4-20mA analog signal, through its dedicated analog input terminals.

Q8: How can I prevent an overload fault (Error E.01) with this VFD?

An overload fault often arises from incorrect motor parameter settings, exceeding the VFD's continuous current rating, or an undersized motor. Double-check and accurately configure the motor's rated current and other parameters. Ensure the ambient temperature is within the specified operating range and that the VFD has adequate ventilation.

Q9: Does this VFD support communication protocols for integration into automation systems?

Yes, the INVT GD10-2R2G-2-B can support communication protocols like RS485 through an optional communication card. This enables integration with PLCs, HMIs, or SCADA systems for remote monitoring, parameter adjustment, and diagnostics.

Q10: What is sensorless vector control, and why is it beneficial for fan applications?

Sensorless vector control offers improved torque response and accuracy compared to standard V/f control, without requiring motor-mounted sensors. For fans, this translates to better speed stability under varying air loads, enabling more precise airflow management and enhanced efficiency, especially in dynamic conditions.
