Hello, I am encountering difficulty changing the settings on my Lenze EVS9323-EP inverter. I have attempted to use different modules such as EMZ9371BC, EMZ9371BB, E82ZBC, and Lecom module EMF2102IBCV001 with no success. When connecting a keypad to the inverter, it only displays a GLOBAL DRIVE INIT message, indicating a communication issue. The Lecom module's green LED blinks, signaling a communication error as well. I have also tried supplying the controller board with an external 24V power source but have not seen any improvements. Testing the voltages on the electrolytic capacitors of the controller board shows they are functioning correctly. The inverter itself appears to be functioning normally based on the status LEDs on the front panel. One example is when the resolver cable is disconnected, causing the LED to change from green to red. Do you have any suggestions on how to resolve this issue?
If you are experiencing issues with an older series servodrive, it may be due to a faulty servodrive or a problem with the display interface or Lecom module connection. To troubleshoot, you can use a "USB to CAN" adapter (EMF2177IB) to connect via CAN. Locate the terminals CAN-Hi, CAN-Low, and CAN-GND on the servodrive and connect them to the adapter's wires. Additionally, remember to adjust the communication settings in the GDC (Global Drive Control) software from LECOM to Systembus CAN for proper connectivity. This can help diagnose and resolve any communication issues effectively.
Hello, upon examining the nameplate of your servodrive, it appears to be quite old. It may be time to consider upgrading to a newer series of servodrive or purchasing a new one from the current series. The old servo series (9300) will only be available for a few more months before it is discontinued. This series has been around for over 25 years, so it may be a good idea to make a decision soon before it becomes unavailable.
I appreciate your feedback. I was able to address a malfunction in the controller's keypad interface and successfully repair it.
It sounds like you've already done a thorough job of troubleshooting! Given that theGlobal Drive Init message indicates a communication problem, it might be worth double-checking all the connections to ensure they're secure and properly seated. Also, have you verified the firmware version on the inverter to see if it aligns with the modules you're using? There could be compatibility issues, especially if the firmware is outdated. Another aspect to consider is whether the modules you're connecting are actually configured for your specific setup; sometimes settings need to be tailored for different applications. If all else fails, reaching out to Lenze support with your specific setup details might provide more targeted assistance. Good luck!
It sounds like you’ve done some thorough troubleshooting already! Given the "GLOBAL DRIVE INIT" message and the blinking green LED, it might be worth double-checking the wiring connections for any loose or incorrectly connected pins, especially between the inverter and the control modules. Sometimes, even a small wiring issue can lead to communication problems. Additionally, if you haven’t already, try resetting the inverter to factory settings, if that option is available, as that might clear up any lingering config issues. Lastly, ensure that the firmware on the modules is compatible and up-to-date with the inverter; mismatches here can often cause communication errors as well. Good luck!
It sounds like you've done quite a bit of troubleshooting already! One consideration might be to double-check the wiring and connections between the inverter, keypad, and any modules you’re using, as a loose connection can often cause communication errors. It’s also worth ensuring that the firmware versions of the modules are compatible with the inverter. Have you looked into using an RS-485 interface for communication if the keypad supports it? Sometimes the settings can get a bit finicky, and a fresh firmware update on both the inverter and any connected modules could help as well. Good luck!
It sounds like you've already done a thorough job troubleshooting! Since you're seeing the "GLOBAL DRIVE INIT" message, it might be worth double-checking the wiring and connections for any loose contacts or faulty cables, as even minor issues there can cause communication problems. Additionally, if the inverter is still in warranty, it could be beneficial to reach out to Lenze's support team directly, as they might have specific insights for your modules and setup. It's frustrating when everything seems okay but still doesn't communicate properly, so I hope you find a solution soon!
It sounds like you've done a thorough job troubleshooting your Lenze inverter! One possible avenue to explore is checking the wiring and connections between the modules and the inverter, as any loose or damaged wires could lead to communication issues as you're experiencing. Also, ensure that the firmware on the modules is compatible with your inverter model; sometimes, mismatch in versions can cause these types of problems. Lastly, if you haven’t already, try resetting the inverter to factory settings—this can sometimes clear out any lingering issues that might not be immediately obvious. Good luck!
