Hello everyone, We've encountered an issue with a couple of servo valves and are looking for any insights on similar occurrences. Following a drop in pressure on 2 servo valves, they quickly returned to their original position, causing the machine to go into fault mode. This is the first time this has happened since the valves were installed 2 years ago. Subsequently, the MSO tags for both valves are displaying MSO.ER 11. According to the manual for the 1756-M02AS, this indicates that the axis is not properly configured. It's puzzling how this could happen after the machine has been operating smoothly for 2 years. My research suggests that re-downloading the program may resolve the issue, but I won't be able to attempt this until Monday. Has anyone encountered a similar situation before? Thank you.
Following a drop in pressure on two servo valves, they swiftly returned to their default position, causing the machine to go into fault. This issue may be related to the loop gain, which is influenced by pressure levels. It appears that a following-error occurred before the system abruptly moved to the home position. It is worth investigating if there is a following-error trap that disengages the servo loops in such situations. Additionally, is this drop in pressure a common issue or is it considered abnormal? It may be possible that a simple reset could resolve the issue.
Avoid downloading the program as it may not solve the issue and only provide a false sense of resolution. The MSO error typically occurs when attempting to activate the servo while the axis is in shutdown mode, faulted, or not properly configured. If in shutdown mode, you will need to programmatically issue a MASR. In case of a fault, a MAFR should be issued. If the axis is not configured, it is likely that the motion group has not synced or there are communication issues, or possibly a missing Line voltage.
Hello! I understand your predicament and it's quite perplexing. From my experience, error MSO.ER 11 could also indicate a potential communication issue between your servo valve and the controller. This can happen due to a variety of reasons - cable issues, interference, or even something like an unexpected power blip. You're right about trying to re-download the program - it may just solve the issue. However, if the problem persists after Monday, I highly recommend you also check the wiring and connections. It's a bit of a wild shot, but sometimes the smallest issues cause the strangest faults.
Hi there, I had a similar issue with the servo valves on a machine at our facility. Our situation was caused by a slight misalignment that occurred over time due to vibration in the machine. It appears fine on the surface but effectively changes the configuration of the axis. This might be your case, too, considering the machine has been running for 2 years without issue. Before you re-download the program, I'd suggest a thorough physical inspection of the machine, to rule out any mechanical problems. It might save you a lot of time and needless troubleshooting.
Hi there! I haven’t encountered the exact same issue, but it does sound like something might have changed in the configuration or settings to cause that fault after two years of smooth operation. Before you re-download the program, I’d recommend checking for any recent maintenance or environmental changes that could have impacted the valves. Additionally, ensuring all connections and wiring are secure might help rule out any physical issues. Hopefully, it’s a smooth fix for you on Monday!
Hi there! I haven't had the exact same issue, but I've seen similar problems with servo valves related to misconfigurations or unexpected changes in the system. It's interesting that it happened after two years of smooth operation—it might indicate a gradual wear or a sudden pressure spike. I'd definitely recommend checking all connections and parameters when you re-download the program. Sometimes, a simple reset can also do wonders! Good luck, and keep us posted on what you find!
Hey there! It's definitely puzzling when issues like this pop up unexpectedly after a couple of years of smooth operation. While your plan to re-download the program is a good start, I’d also recommend checking the physical connections and ensuring there aren’t any loose wiring or signs of wear on the valves themselves. Sometimes environmental factors can lead to unexpected drops in pressure, even if everything seems fine at first. If the error persists after the program reload, it might also be worthwhile to look into the configuration settings and any recent changes made in the system that could have affected the servo functionality. Good luck, and I hope it gets resolved quickly!

Answer: - The error code MSO.ER 11 indicates that the axis is not properly configured according to the manual for the 1756-M02AS.
Answer: - One possible solution to resolve the MSO.ER 11 error is to re-download the program, as suggested by the manual.
Answer: - The sudden drop in pressure on the servo valves could have various causes, such as a malfunction in the configuration, wear and tear over time, or external factors affecting the valves.
Answer: - It is not common for servo valves to return to their original position after a pressure drop, as this behavior can lead to the machine going into fault mode.
Answer: - Servo valves should be regularly inspected and maintained according to the manufacturer's recommendations to prevent issues like MSO.ER 11 from occurring unexpectedly after a long period of smooth operation.
