It has to do with energy. When a VFD is using energy to turn a motor then the energy is being used for rotational motion in the motor. When a motor is turning by itself due to a load turning the motor due to gravity then energy is going from the motor back to the VFD. Energy needs to be dissipated to a braking resistor if a line regen unit is not installed. If a braking resistor gets too hot there is a possibility of components melting or even catching something on fire. This is why having the correct size braking resistor and a VFD with protection functions is essential for safe operation.

@@KEBAmerica thanks But there is meny of same machin 150 number witch works in same condition and situation just one of them is hot. I have cheked all of wireing and connections and motor but appearantly there is no problem !

That is a good question for Nippon Pulse. Feel free to as them about bearing wear and what would be best for your application.

Thank you. We have worked to optimize the layout of our facility to better serve our customers with high quality automation products. Take care!

We appreciate the kind words. We are proud to manufacture our high-quality products here in North America. And yes, Joe did a great job talking about the different aspects of our manufacturing process. Cheers!

I'm not sure what you're asking. If you have questions, feel free to contact us about KEB products.

We're glad you find it helpful! Let us know if you or your company are interested in learning more about KEB automation. Have a great day!

Thanks for your questions. For specifics on this type of application, please reach out to us here: www.kebamerica.com/contact We hope to hear from you soon. Thanks for watching!

Thank you for pointing this out. The F5 drive shown here is our previous generation of drives that do not utilize our easy startup wizards. Our current F6 and S6 drives allow a simplified startup procedure. If you want to learn about starting up a motor using the F6 drive you can check out this tutorial: www.kebamerica.com/blog/keb-f6-drive-start-up-procedure If you want to see an S6 startup (very similar to the F6), you can watch the video or follow along with this article: www.kebamerica.com/blog/keb-s6-servo-drive-basic-start-up Let us know if you have any other questions or comments. Have a great day!

Is this for a large scale industrial printer or a smaller desktop 3D printer? What you select depends on the budge, size, and purpose of the printer.

@@KEBAmerica what you select is solely based on the amount of precision and accuracy you want.

That should reset by power cycle or controller. E.nOL means the error E.OL cooldown period is over and can get reset now. If you have further questions you can call or email us. Thank you.

Are you asking about a KEB motor or any PM motor? There are several types of sensors that are covered in another KEB Shorts video here: ruclips.net/video/7DGeWGxlcYk/видео.html

If this error occurs after every power up then you are correct. There is likely a hardware issue. For further assistance, contact your machine manufacturer. Thank you!

We are not sure what 802.6 means with the little information you have given. For specific help on your application you should contact your machine manufacturer and give them the part number of the F5 drive and the keypad operator? It may not be a board issue. It could be an issue with the setup in the drive. Is this a drive you bought off the internet or through a distributor? It's hard to diagnose without more specific information.

We are a small company that repairs industrial equipment. This F5 Keb model 22F5HAR-YV10 did not turn on when it arrived at our laboratory. After repairing the main problem, every time we connect 440 VAC to the equipment the operator panel shows only five zeros that turn on and off continuously. We tried to modify the parameters, but the only key combination that changed anything on the operator panel was pressing the ENTER + FUNC keys and 802.6 appears on the display. The operator panel has the model 00F5060-1000 (OPERATOR F5 STANDAR KEYBOARD Rev C). This type of operator panel does not have an RS232 connection to the computer to backup the parameters. Is there a way to do this backup with this type of operator panel?@@KEBAmerica

This is likely an issue with the control board or the internal power supply. With this type of issue we recommend that you send the drive into our service department for proper diagnosis, repair, and load testing. However, if you want to diagnose and repair the drive yourself and you have the tools, this information should help you with diagnosis. Just be aware we are not responsible for any damage occurring from your efforts. First, if you have a 0058060-0040 USB converter you can connect to the drive with Combivis 6 directly into the X4A port that the operator plugs into. You can also power the control card only using an external 24vdc supply connected to pins X2A.21 (+24vdc) and X2A.22 (0vdc). There is no way for us to properly diagnose the actual issue(s) unless we can evaluate here in our Service and Repair Department.

Thank a lot my friend@@KEBAmerica. We have to buy this USB Converter to connect the VFD with Combivis. If we do not find the problem, ¿do you have a service center in Mexico?

What type of application is this F5 inverter running? When is this E.BLC error occuring?
