FAQs

What is the power rating of the INVT GD10-0R7G-4-B?

The INVT GD10-0R7G-4-B has a rated power of 0.75 kW, which is equivalent to 1 horsepower. This makes it suitable for a wide range of smaller to medium-sized industrial motors.

This power rating is ideal for applications requiring precise speed control without excessive load demands. It efficiently manages motor performance for tasks like small pump or fan operation.

The 1 HP capacity ensures that the VFD can handle the startup surge and running requirements of compatible three-phase motors effectively.

Can the INVT GD10-0R7G-4-B be used with single-phase motors?

No, the INVT GD10-0R7G-4-B is specifically designed for 3-phase motors. It requires a 3-phase input power supply and outputs a 3-phase power signal to the motor.

Using this VFD with a single-phase motor is not possible and could lead to damage to both the motor and the drive. Always match the VFD's phase configuration to the motor's.

For applications using single-phase motors, a different type of variable speed drive designed for single-phase output would be necessary.

What type of control does the INVT GD10-0R7G-4-B support?

The INVT GD10-0R7G-4-B supports both V/f (Volts per Hertz) control and sensorless vector control. V/f control is a simpler method for basic speed regulation.

Sensorless vector control offers more advanced performance, providing better torque response and speed accuracy without requiring a motor encoder. This is crucial for dynamic loads.

These dual control modes make the GD10-0R7G-4-B versatile for a broad spectrum of applications, from simple fan speed adjustments to more demanding process control.

What is the typical operating temperature range for this VFD?

The INVT GD10-0R7G-4-B operates reliably within an ambient temperature range of -10°C to 40°C. This range ensures consistent performance in most industrial environments.

Exceeding these temperature limits, especially the maximum of 40°C, can lead to derating or potential damage. Proper ventilation is essential to maintain performance.

If operating in environments outside this range, consider supplementary cooling solutions or selecting a VFD model with a wider temperature tolerance.

How is the INVT GD10-0R7G-4-B installed?

This VFD can be mounted either on a wall or using a DIN rail, offering flexibility in installation. It features a compact, IP20 rated enclosure for protection.

Ensure the drive is installed vertically to allow for proper heat dissipation through its heatsink. Avoid mounting in areas with excessive dust, moisture, or direct sunlight.

Always follow the wiring diagrams in the manual for correct power, motor, and control signal connections. Adequate spacing for ventilation around the unit is crucial.

What are the communication capabilities of the GD10-0R7G-4-B?

The INVT GD10-0R7G-4-B offers optional RS485 communication. This allows for integration into networked control systems.

With RS485, you can remotely monitor parameters, adjust settings, and diagnose issues. It's key for IIoT integration and SCADA systems.

This communication capability enhances automation and provides greater control over the motor and process.

What is the output frequency range of this drive?

The output frequency range for the INVT GD10-0R7G-4-B is from 0.00 Hz up to 5000.00 Hz. This wide range allows for very precise speed control.

The ability to go down to 0.00 Hz means the motor can be held at zero speed or used for positioning applications. The high upper limit suits high-speed applications.

This extensive frequency capability ensures the drive can meet the requirements of diverse motor speeds and process demands.

What type of protection does the IP20 enclosure offer?

An IP20 enclosure rating signifies protection against solid objects larger than 12mm, such as fingers. It prevents accidental contact with internal components.

However, IP20 enclosures do not offer protection against water or dust ingress. Therefore, the drive must be installed in a clean and dry environment.

This level of protection is standard for many indoor industrial drives where environmental conditions are controlled.

What are common fault codes for the INVT GD10-0R7G-4-B?

Common fault codes include OC (Overcurrent), OV (Overvoltage), UV (Undervoltage), and OL (Overload). These indicate specific issues that need to be addressed.

For example, an OC fault typically means the motor is drawing too much current, possibly due to a short circuit, excessive load, or rapid acceleration.

Each fault code has a corresponding explanation and troubleshooting procedure in the user manual to help resolve the issue.

Is the INVT GD10-0R7G-4-B suitable for very high-speed applications?

With an output frequency range up to 5000.00 Hz, the GD10-0R7G-4-B is capable of driving motors at significantly higher speeds than standard 50/60 Hz applications. This is useful for specialized machinery.

However, the motor itself must be rated for such high speeds, and considerations like bearing lubrication and mechanical balancing become critical at these RPMs.

Always consult the motor manufacturer's specifications and ensure the application’s mechanical components can safely operate at the intended high frequencies.
