---

1. **Limited Power Rating (2.3 HP / 1.7 kW)** Not suitable for high-power applications requiring larger motors (e.g., pumps, conveyors, or heavy machinery). Users with higher load demands may need a more robust VFD.

- Advanced PLC integration

- Remote monitoring via IoT/cloud

- Multi-motor control

- High-resolution parameter tuning

- Built-in communication protocols (e.g., Modbus, Profibus) for complex automation

3. **No Built-In Regenerative Braking** Unlike some higher-end VFDs, it does not handle regenerative energy (e.g., from descending loads), which can limit its use in applications requiring energy recovery.

4. **Single-Phase Input Limitation** While it supports 115/230V, it is not a three-phase VFD. Three-phase applications may require additional equipment (e.g., a phase converter), increasing complexity and cost.

5. **Dependence on Manufacturer Support** KB (Kubota) is primarily known for pumps and agricultural equipment, and their VFD line may not have the same level of technical support or documentation as dedicated VFD manufacturers (e.g., Siemens, Schneider, or ABB).

6. **Potential for Higher Maintenance Costs** As a hybrid drive, it may require more frequent calibration or firmware updates compared to traditional VFDs, depending on usage conditions.

7. **No Built-In Energy Feedback** Unlike some modern VFDs, it does not provide real-time energy consumption data or feedback, making it harder to optimize energy use in large systems.

8. **Limited Customization** Parameters and settings may be less flexible than those in high-end VFDs, restricting fine-tuning for specific applications.

9. **Potential for Compatibility Issues** If integrating with legacy systems or non-standard motors, additional troubleshooting may be required to ensure seamless operation.

10. **Resale Value** VFDs from niche manufacturers (like KB) may have lower resale value compared to industry-standard brands, which could be a consideration for long-term investments.
