I recently acquired a pre-owned PowerFlex 525 AC Drive and attempted a factory reset by changing parameter t053 to 2. However, I am now unable to activate the drive in RUN mode despite both parameters 46 and 47 being set to 1. Any assistance with resolving this issue would be highly valued.
If you're experiencing issues, it's recommended to reset the digital inputs such as T62, T63, T65, T66, T67, T68 to their default settings or configure them appropriately. Additionally, consider connecting S1 and S2 to S+ for a safer off option. Keep in mind that previous users may have removed the factory default jumpers.
User larbi16 is seeking assistance with a PowerFlex 525 AC Drive that they purchased second-hand. After changing parameter t053 to 2 for a factory reset, parameters 46 and 47 are now both set to 1, but the drive cannot be put into RUN mode. Any help in resolving this issue would be greatly appreciated. For more information on troubleshooting and getting the drive up and running, please refer to the following link: https://literature.rockwellautomation.com/idc/groups/literature/documents/qs/520-qs001_-en-e.pdf.
Hey, it sounds like you've run into a bit of a hiccup with your PowerFlex 525. From my experience, after a factory reset, remember to check not only parameters 46 and 47, but also parameter 1, which must be set to 0 to allow for remote operation. Also, I'd suggest rechecking all your connections after the reset just to rule out any physical issues. Good luck and let us know how it goes!
You may want to double-check the connections, especially the control wiring. Make sure everything is properly wired and the terminals are tightened. Also, consider checking parameter 36 (Start I/O) - it should be set to 01 if you're controlling the start via terminals. If everything seems fine yet the problem persists, you may be dealing with a more serious hardware issue. However, try these tips first and let us know how it goes.
Have you checked parameter 56? It’s the one defining your reference source, and it can sometimes cause conflicts if it's not set correctly. Also, review the wiring diagrams in the manual to ensure you have everything connected correctly after the reset. The PowerFlex 525 can be a bit finicky sometimes, but once it's set up properly, it tends to run smoothly.
It sounds like resetting the drive likely put the parameters in a different group. I'd suggest first ensuring the drive logic command/feedback option 2 is selected in parameters 36/37 (Source of Operation) to have full control over the drive. Once you set the parameters correctly, attempt to switch it back to RUN mode. If the issue still persists, do a quick check over the electrical connections, as such problems often stem from simple human errors such as loose wiring or incorrect wiring connections.
It sounds like you're dealing with a bit of a tricky situation! After a factory reset, it's not uncommon for settings to revert back to defaults, which might include parameters like motor control settings or enabling the drive itself. I’d recommend checking the motor parameters (like motor horsepower, rated voltage, and current) to ensure they are correctly set post-reset. Additionally, double-check that the control source is set correctly, as sometimes it defaults to things like "local" or "remote." If everything seems right and it still won’t go to RUN mode, it might be worth consulting the user manual for troubleshooting steps or reaching out to Rockwell support for further assistance. Good luck!
It sounds like you’re on the right track with the reset, but I’d suggest double-checking that all the necessary parameters for your specific application are set correctly. Sometimes additional settings like FLA (Full Load Amps) or the control method (like V/f or Vector) may need adjusting after a factory reset. Make sure the drive isn’t in a fault state, as that could also prevent it from running. If all else fails, a good idea might be to cycle power to the drive after making changes; sometimes it just needs a fresh start!
