Fault Code 1: Overvoltage (E.OV)

In the Mitsubishi D700 VFD, the error code E.OV indicates an overvoltage condition. This fault occurs when the input voltage exceeds the specified range. It is important to address this issue promptly as prolonged exposure to overvoltage can damage the drive and connected equipment.

Fault Code 2: Undervoltage (E.UV)

The fault code E.UV signifies an undervoltage condition in the Mitsubishi D700 VFD. This fault occurs when the input voltage drops below the specified range. It is crucial to investigate and resolve this issue to prevent erratic drive behavior and potential motor damage.

Fault Code 3: Overcurrent (E.OC)

When the fault code E.OC is displayed on the Mitsubishi D700 VFD, it indicates an overcurrent condition. This fault occurs when the current drawn by the drive exceeds its rated capacity. It is important to identify the cause of the overcurrent, such as a mechanical overload or a fault in the motor, and take appropriate corrective measures.

Fault Code 4: Overheat (E.HS)

If the Mitsubishi D700 VFD displays the fault code E.HS, it means that the drive has detected an overheat condition. This fault occurs when the internal temperature of the drive exceeds the safe operating limits. Proper cooling and ventilation should be ensured, and any obstructions or malfunctions of cooling fans should be addressed to prevent further overheating.

Fault Code 5: Communication Error (E.CN)

The fault code E.CN on the Mitsubishi D700 VFD indicates a communication error. This fault occurs when there is a problem with the communication between the drive and the control system. It is important to check the communication cables, connectors, and settings to ensure proper connectivity and avoid any interruptions in data exchange.

4. If the fault code persists, try replacing the communication cable with a new one to rule out any cable issues.
5. If none of the above steps resolve the issue, consult the Mitsubishi D700 VFD’s user manual or contact their technical support for further assistance.

Remember to always exercise caution when troubleshooting electrical equipment and follow proper safety procedures.

Why am I receiving fault code U.F on my Mitsubishi D700 VFD, and how can I fix it?

Fault code U.F on a Mitsubishi D700 VFD indicates an undervoltage fault. This fault occurs when the voltage supplied to the VFD is lower than the minimum required level. To fix this issue, you should check the input power supply and ensure it meets the recommended voltage levels. Additionally, inspect the wiring connections for any loose or damaged cables. If the problem persists, consult the manufacturer’s manual or contact a qualified technician for further assistance.

What does fault code E.AO signify on a Mitsubishi D700 VFD, and what steps should I take to address it?

Fault code E.AO on a Mitsubishi D700 VFD signifies an analog output voltage abnormality. To address this issue, the following steps should be taken:
1. Check the connections and wiring of the analog output terminal.
2. Ensure that the analog output settings are configured correctly.
3. Verify the integrity of the connected equipment or devices receiving the analog output signal.
4. If necessary, consult the user manual or contact Mitsubishi technical support for further troubleshooting guidance.

How do I reset a fault code on a Mitsubishi D700 VFD?
