Troubleshooting Powerflex 755 VFD Error Code 10118: I1 HS Fan PS Low

Question:

I am encountering an alarm (error code 10118) on my Powerflex 755 VFD indicating an issue with I1 HS Fan PS Low. Despite my limited experience with this drive, I have identified the problem to be at the P6 connector where there is a lack of voltage. Has anyone else faced a similar issue with this drive before? I am concerned that the board might be faulty. Any insights or advice on troubleshooting would be greatly welcomed.

It appears that there are a few public articles on this topic. There are two specific IDs related to PowerFlex 755 alarms: ID BF22956 and ID BF5430. These alarms involve issues such as Main Inverter Fan Failure and Auxiliary Power Supply failure for PowerFlex 755 frame 8 and higher. To address these faults, it is recommended to conduct power and fuse checks inside the drive's control boards. Resetting the fault may require adjusting internal parameters or performing a power cycle. For Alarm 10118, the suggested actions include: 1. Checking for a 230V supply on the inverter power supply board at connector P6. 2. If voltage is present, consider replacing the inverter power supply board. 3. If there is no voltage, inspect the control power transformer, primary and secondary fuses, and wiring harness for any issues.

I am grateful for the feedback you provided. Your input means a lot to me.

FatGuy27 expressed gratitude for the feedback received, showing appreciation for the insight provided. It seems like you are already on the right track. Keep up the good work!

Ian, thank you for your assistance with this issue. With the drawing you provided, I was able to resolve the problem in just 30 minutes. It turned out that the problem was a blown F6.

Yes, I've encountered a similar problem on a Powerflex 755 in the past. In my case, the error code was due to a loose connection at the fan power supply terminals. I would suggest you check the wiring at the P6 connector thoroughly to ensure it's secure. If the problem persists, it may be worth checking the fan health status in the drive parameters. Given that different fans have different voltages, it's also possible that the fan might be incompatible. There's a chance it might be the board, but exhaust these other possibilities first before coming to that conclusion.

It seems like you've done quite a bit of troubleshooting already, which is great. Based on my experience with PowerFlex drives, your issue could indeed point to a faulty board. But before jumping into component replacements, you might want to assess the health of your wiring. Ensure that the connector is not loose and the wires are not frayed or broken. The lack of voltage at the P6 connector could be due to a simple wiring issue. If the problem persists despite good wiring, then a board failure might be the culprit. Also, keep in mind the ambient temperature, as high temperatures can cause the fan to run constantly, potentially leading to premature failures.

I haven’t dealt with that exact error on the Powerflex 755, but I can relate to similar issues on VFDs where fan supply problems are often linked to connectors or wiring. It sounds like you’re on the right track with the P6 connector; checking for loose connections or any signs of damage can often reveal the culprit. If voltage is absent, you might also want to check the power supply feeding that connector or any related fuses. It could also be worthwhile to consult the manual for any specific diagnostic procedures outlined for error 10118. Don't hesitate to reach out to support if you suspect a faulty board—they usually have great troubleshooting guides! Good luck!

I’ve dealt with the Powerflex series a few times, and that error code typically points to a problem with the cooling fan circuit. Before jumping to the conclusion that the board may be faulty, I’d suggest checking the connections at the P6 connector for any loose wires or corrosion that could be causing the voltage drop. It’s also worth testing the fan itself—sometimes, if the fan isn’t spinning or is blocked, it can trigger that alarm. If everything looks good and you still have issues, then you might need to consider further diagnostics or even look into any recent updates or recalls on that specific model. Good luck!
