2. Set P0.01 to the desired value according to your needs, such as “1” to prohibit changes to all parameters, or “3” to restore all parameters except motor group parameters to their factory settings.

II. External Control and Speed Adjustment Settings

2.1 External Terminal Forward and Reverse Control

The V&T Inverter V5-H supports forward and reverse control of the motor through external terminals. Users need to connect the FWD (forward) and REV (reverse) terminals to the control signal source, such as a PLC or button switch. At the same time, corresponding parameters need to be set in the inverter:

1. Enter the operation panel menu and locate the “Run Command Given Mode” parameter (P0.06).
2. Set P0.06 to “1”, indicating that the run command is given through terminals.

2.2 External Potentiometer Given Frequency Speed Regulation

By connecting an external potentiometer to the AI1 (Analog Input 1) terminal of the inverter, users can achieve speed control of the motor frequency. The specific steps are as follows:

1. Wiring: Connect the output terminal of the external potentiometer to the AI1 terminal of the inverter, and connect the COM terminal of AI1 to the common terminal of the inverter.
2. Parameter Setting:
   • Enter the operation panel menu and locate the “Open-Loop Main Given Mode” parameter (P0.04).
   • Set P0.04 to “1”, indicating that the frequency is given by AI1 analog input.
   • Set the AI1 analog input curve (P6.00) as needed to achieve linear or nonlinear speed regulation.

III. Fault Codes and Solutions

The V&T Inverter V5-H features a comprehensive fault diagnosis function that can display fault codes and fault information in real-time, helping users quickly locate problems. The following are some common fault codes, their meanings, and solutions:

3.1 E.oc1: Overcurrent Protection During Acceleration

Meaning: The inverter detects an overcurrent phenomenon during acceleration.

Solution:

• Check if the grid voltage is too low.
• Extend the acceleration time to reduce load mutation.
• Check if the motor parameter settings are correct.
• Consider replacing with a higher-power inverter.

3.2 E.oc2: Overcurrent Protection During Deceleration

Meaning: The inverter detects an overcurrent phenomenon during deceleration.

Solution:

• Extend the deceleration time.
• Use a suitable energy dissipation braking component.
• Check the motor parameter settings.

3.3 E.AUt: Self-Tuning Fault

Meaning: The inverter encounters a fault during self-tuning.

Solution:

• Ensure that the motor is in a stationary state before performing self-tuning.
• Check if the motor wires are properly connected and within the specified length.
• Reset the P9 group motor parameters according to the motor nameplate.

3.4 E.oL2: Motor Overload Protection

Meaning: The inverter detects motor overload.

Solution:

• Check if the load is too heavy or if the motor is jammed.
• Adjust the inverter overload protection parameters (P9.16, P9.18).
• Check if the motor is overheating, and replace it if necessary.

IV. Conclusion

The V&T Inverter V5-H manual provides users with detailed operation guides and troubleshooting methods. By mastering the functions of the operation panel and parameter setting methods, users can conveniently control and manage the inverter. At the same time, understanding common fault codes and their solutions can help users quickly locate and resolve issues, ensuring the stable operation of the inverter. In practical applications, users should also make flexible adjustments and optimizations based on specific needs and site conditions.
