Siemens G120 VFD – Fault Codes and Troubleshooting Steps
Siemens G120 drives are equipped with an array of fault and alarm codes, each representing specific issues that can arise during operation. Here is a summary of the most prevalent fault codes and their meanings:
- F01000 / F01015: Indicates an internal software error.
- F01001: A floating point exception error.
- F01018: Power-up procedures have aborted multiple times.
- A07011 / F07011: Indicates that the motor has overheated.
- F30001: An overcurrent has been detected; output is turned off to protect the drive.
- F30002 / F30003: Overvoltage or undervoltage conditions have raised concerns regarding the DC-link voltage.
- F30004: The inverter has overheated.
- F30011: A line phase failure has occurred.
- F30015: A motor cable phase failure is detected.
- F30021: A ground fault has been detected.
General Fault-Handling Guidance for Siemens G120
For effective troubleshooting of these fault codes:
- Use parameter r0947 to read current and past faults. If you want to ascertain the related error values, access r0949.
- If you encounter thermal or overcurrent faults, such as F07011 and F30001, check for excessive load and confirm that the motor and inverter sizes are appropriate.
- Careful inspection of wiring for potential short circuits, correct connections, and ground faults is critical. Always ensure that motor parameters match the actual motor in use.
- For power and line faults such as F30002, F30011, and F30015, verify supply voltage and phase sequence, checking cable integrity as you go.
- In numerous cases, a power-cycle reset will clear faults, but persistent issues may necessitate further service intervention.

Wiring Tips for Siemens G120 VFDs
Proper wiring is essential for improving VFD performance and avoiding faults. Here are essential wiring tips when working with Siemens G120 drives:
- Control wiring should use recommended twisted-pair or shielded cables for analog or digital signals to minimize interference.
- Be mindful of the typical terminal arrangements:
- Digital Inputs: Start/Stop, Fault Reset
- Analog Inputs: Speed Reference (e.g., Terminal 11 = AI1–, Terminal 12 = AO0+)
- It’s crucial to shield all control cables and ground them adequately to prevent issues with electromagnetic compatibility (EMC).
- For the start/stop circuit, jump terminal connections appropriately (e.g., 34, 28, 69 on some models) and ensure you share 24 V across switch commons.
- Always double-check the grounding and potential differences between the drive and control circuits to prevent faults before they occur.
With the knowledge of these fault codes and wiring best practices, you can proactively address issues with Siemens G120 VFDs. Don’t hesitate – Shop this category for your Siemens VFD needs today!
ABB ACS VFD – Fault Codes and Troubleshooting Steps
When it comes to ABB ACS drives, such as the ACS355, ACS550, and ACS800, fault detection and troubleshooting are equally crucial. Common fault codes encountered include:
- F0001: Indicates an overcurrent condition, possibly due to a short circuit or ground fault.
- F0002: An overvoltage situation where the DC link voltage exceeds limits.
- F0003: An undervoltage condition where supply voltage is too low.
- F0004: A motor overload or overtemperature is detected.
- F0021: An earth fault is identified with current sensed to ground.
- F0022: Indicates a motor stall or blockage.
Handling ABB Faults Effectively
For effective troubleshooting of ABB fault codes, follow these guidelines:
- In cases of overcurrent/overvoltage, check motor and drive sizes, ensuring they are well matched. Inspect all cables for shorts or ground faults.
- If faults occur during startup, consider reducing the ramp-up speed (acceleration) to mitigate risks of tripping.
- For earth faults or phase faults, ensure that all motor cables are properly connected and insulated. If insulation breakdown is detected, you’ll likely need to replace cables or motors.
To reset faults in ABB drives:
- Most faults can be cleared by pressing the reset button or cycling power after making corrections.
- You can review the event log via the control panel or through software tools like Mint WorkBench.
- Be wary of persistent faults, as they might indicate potential hardware damage requiring further investigation.

Wiring Tips for ABB ACS Drives
When wiring ABB ACS drives, ensure you follow these recommended practices:
- Correct terminal mapping is crucial for control and power circuits; always consult ABB manuals for specifics.
- Utilize shielded, well-earthed control cables to mitigate noise and signal integrity issues.
- Verify analog signal integrity to prevent speed reference or feedback issues.
- When establishing a start/stop connection via digital input, short the appropriate DI terminals as specified in the manual.
Implementing the right wiring techniques minimizes the risk of errors and optimizes the performance of your ABB drives. If you’re ready to advance your operations, Shop this category for components that suit your ABB systems.
