20 Most Recent Inverter Yaskawa F7 Drive Questions & Answers

Canadian Prefered Friends #5?? Cherries picked Fresh??

every thing is working fine, the battery shows 13.28volts, the Mosfets are good, cant understand still why the hell it shows overload, without connecting any load to it, give me a reasonable solution if any one can.

What error code is displayed? Status of indicator lights? Solid on or blinking? The owner's manual has a comprehensive list of error codes and solutions. Your problem could possibly be corrected by adjusting the settings.
Here's a link to the manual: Chapter 6 will help you tremendously.

Try this link, as you didn't indicat what model you have. There are manuals in pdf form you can download. They will have a fault code listing if you can determine what model you have

sounds like as transistor problem check transistors on heat sink and make sure no wires have come unsoldered and also check with a test meter to see if transistors are allowing current or have closed if closed no current replace.

Error E. OH (overheat power module) on a KEB F5 Inverter indicates that the power module is overheating. This can be caused by a variety of factors, including a malfunctioning cooling system, a faulty power module, or a problem with the wiring or connections. To troubleshoot the issue, you can try the following steps:

1. Check the cooling system for any visible signs of damage or malfunction, such as a clogged air filter or damaged fan.
2. Check the power module for any visible signs of damage or malfunction, such as burnt or damaged components.
3. Check the wiring and connections to ensure that they are secure and properly connected.
4. Check the F5 Inverter's fuse and circuit breaker to ensure that they are functioning properly.

If these steps do not resolve the issue, it's best to contact a professional repair service or the manufacturer for further assistance. They will be able to diagnose the problem and recommend the appropriate repairs. It's also a good idea to stop using the F5 Inverter until the issue has been resolved, as continuing to use it may cause further damage.

It's generally not recommended to run a KIPOR 3000TI Inverter without the Kipor 66284 DC receptacle. The DC receptacle is an important safety feature that helps to protect the inverter and any connected equipment from damage. If it has been removed, it's possible that the inverter may not function properly or may be at risk of damage. If the DC receptacle has been removed and you are experiencing issues with the inverter, it's best to contact a professional repair service or the manufacturer for further assistance. They will be able to diagnose the problem and recommend the appropriate repairs. It's also a good idea to stop using the inverter until the issue has been resolved, as continuing to use it without the DC receptacle may cause further damage or pose a safety risk.

If your Power Star W7 has a dead display and no output, it's possible that there is an issue with the power supply or the display itself. Here are a few steps you can try to troubleshoot the issue:

1. Check the power cord and outlet to ensure that the W7 is properly plugged in and receiving power.
2. Check the power supply for any visible signs of damage or malfunction.
3. Check the display for any visible signs of damage or malfunction, such as cracks or loose connections.
4. Try resetting the W7 by unplugging it and waiting a few minutes before plugging it back in.
5. Check the owner's manual for any troubleshooting tips or information on common issues.

If these steps do not resolve the issue, it's best to contact a professional repair service or the manufacturer for further assistance. They will be able to diagnose the problem and recommend the appropriate repairs. It's also a good idea to stop using the W7 until the issue has been resolved, as continuing to use it may cause further damage.

Most likely the battery volts are displaying correctly. There is a voltage drop on the battery due to its internal resistance, when you connect a supply the voltage drop is less. If you were to put a new battery on it it might reduce the voltage drop, as long as the battery is designed for the current load it's taking. If it's working I wouldn't worry, but if the voltage continues to drop with use I'd be thinking it needs a new battery. (Assuming the battery is charging correctly)

I may miss the point here. If the question is how to clear the error, page 57, item 4.7 Error Messages, of the KEB instruction manual may be of use. https://www.manualslib.com/manual/1293218/Keb-Combivert-F5.html?page=55#manual Here is information about the error code: KEB Error "E. OP" ERROR overpotential (voltage) 1 Voltage in the DC-link cicuit is too high. Occurs if the DC-link circuit voltage exceeds the permisible value. Causes: - poor controller adjustment (overshooting) - input voltage too high - interference voltages at the input - deceleration ramp to short - braking resistor defective or too small Given the very technical nature of the KEB, I lean toward referring to the manufacturer's support. There are quite a number of KEB YouTube videos and a number of supporting documentations available on the web. Perhaps the following will be of use if not an entire misdirection: https://www.kebamerica.com/elevator-support/ https://www.kebamerica.com/products/f5-inverter/
