Hello everyone, I have encountered an issue with a flashing red light on the FDBK indicator, indicating that the axis servo loop error tolerance has been exceeded. I am unsure of what is causing this problem. Has anyone experienced this issue before? Any assistance would be greatly appreciated. Thank you.
rvtran inquired: Greetings everyone, I am encountering the issue of a flashing red light on the FDBK indicator, with the manual indicating that it signifies an axis servo loop error tolerance being exceeded. I am unsure of the cause behind this issue. Has anyone experienced this problem before and if so, could you please offer assistance? Any insights would be greatly appreciated. Thank you. I am facing the same problem, have you managed to resolve it and if so, would you be able to share your solution?
A fault occurs when the position error goes beyond the preset axis limit, leading to a discrepancy between the feedback and the commanded analog position. This issue could arise from encoder malfunctions, encoder slippage, or physical constraints preventing the axis from moving as directed.
I'm encountering a recurring issue where the axis fault displayed is actually related to a module fault. Is there a more effective solution to resolve this problem? I've attempted re-inserting the module into the backplane and power cycling the equipment, but the issue continues to persist at a higher frequency. Any advice on troubleshooting this issue would be greatly appreciated.
Hi there! I've encountered the same issue before with my servo loop. In my case, it turned out to be an encoder issue - the feedback device wasn't properly aligned with the motor. I'd suggest checking the alignment first, and if that's not the problem, you might want to look into the possibility of any software glitches or even a motor damage. Hope this helps!

Answer: 1. What does a flashing red light on the FDBK indicator of an Allen Bradley 1756-M02AE axis servo system indicate? - A flashing red light on the FDBK indicator signifies that the axis servo loop error tolerance has been exceeded.
Answer: - Possible causes could include issues with the feedback device, wiring problems, tuning parameters, mechanical issues, or software configuration errors.
Answer: - To troubleshoot this issue, you can check the feedback device connections, verify the wiring integrity, review and adjust the tuning parameters, inspect for mechanical issues such as binding or misalignment, and review the software configuration for any errors.
Answer: - It is recommended to follow a systematic approach when troubleshooting, starting with checking the feedback device and wiring, then moving on to tuning parameters, mechanical inspection, and software configuration review.
Answer: - Common solutions may include recalibrating the feedback device, adjusting the tuning parameters, ensuring proper mechanical alignment, and verifying the software configuration settings.
