Hello Stephen The first thing you have to do is make sure that the motor is connected for 220 volt three phase How do you know? your motor must have this connection info on the name plate It must show 220v Delta connection and 380 or 400 v star connection. connect your motor in Delta ie the motor connection links are connected from U 1 to V2, U1 to W2 and V1 to U2. Ok Now for the restof it You have asmall book that came with the inverter so go to page 9 and you will see the drawing for mm440 at the bottom you will see the connection for the speed pot. which is 1,2,3,4, wire in as shown make sure the wiping connection is in 3..now wire in a switch across 9 which is the common and 5 this starts and runs the inverter when you open the switch the inverter will ramp down and stop.... IF YOU look at page 8 it shows how delta and star is connected at the motor..... now go to page12 for this you must have the power on to the inverter.. as you enter the parameters they come up in sequence as you enter the info...on par 700 put in 2 also at 1000 put in 2 set p1080 at 0.0...p 1082 at 50 P3900 at1 This should get you up and going

F0022 - Hardware Monitoring Active (as Im sure you are aware) This cannot be 'cleared' without a repair. Likely several components internally need to be replaced.... if you can get them. There are too many possibilities to list here and recommend you dont spend your time trying to repair it yourself. It may well be in vein! Consider sending it for repair or service exchange.

Likely to be IGBT fault. Unless its a large drive I would service exchange it or bin it. Not worth the hassle.

Always allow the DC link voltage to dissipate fully before working on inverters. THEY CAN AND WILL KILL YOU if you don't know what you are doing. Screwed to the heat sink inside, is a little temp sensor that plugs on to the PCB. If it hasn't come unplugged, you can test it by metering the resistance of it as you heat it with a hot air gun. Remove it completely to test, you don't want to overheat everything else. The resistance should drop rapidly and there isn't much point in heating it below 150 ohms as you don't want to cook it! Im sure you can figure out how to test the PCB etc from here. If you can't then Im not going to tell you. You must be competent to be meddling with lethal voltages! Sorry.

This is most likely a fault with the IGBT even if it meters out correctly. They can be replaced but the cause cause of the fault in the first place may still be present and might damage it again. Occasionally there are further issues from faults like this so I would give some thought to doing a service exchange with a repair company.

Depends what you have digital output 1(terminals 19/20) programed as. Check P0731

may be the BOP is not correctly connected
or the supply provided for 2phase has to be interchanged

Hi, this issue could be caused by a number of things from simple dirty connections internally to multiple component failure. I am unaware of your competency level so am reluctant to advise component diagnosis given the potentially lethal voltages that you may encounter. I would recommend a third party repair company take a look at it but new spares are pretty hard to source as are second user spares, so prepare yourself for it to be beyond economical repair. Where abouts are you based?

A bit late but it might be of use to someone..... Siemens have published a pdf document about this Item-ID: 22445905 I found it here - http://support.automation.siemens.com - but their search facility is a little hit and miss! A quick google usually brings it up top of the results.

what a fault 001

jst chk out the connection of the plc and find that the resistence of 500 ohms linked with 10v which converts 10v to 4-20ma is working if it is then it will work or check the drive's connection n parameters of P1300 & communication parameters

Why do you want to run the motor in the delta configuration? The VFD will change the speed to anything you want to do. The delta and Wye connections are normally used to change the speed of a motor. That's what the VFD is for...?? If you need further help, I’m available over the phone at https://www.6ya.com/expert/craig_3fa289bf857b1a3c

Just connect it to the battery. Normally you do it via the power outlet formerly called a cigar lighter. https://www.google.com/search?q=3000+watt+inverter ..

The water has shorted it out. Water and electronics is a BAD mix. OLP (Overload protection indicator): Indicates the inverter will shut down due to a short circuit or overload protection. the inverter cools down, the indicator will turn off automatically. Feb 14, 2023

Pure Sine Wave (ISW) Inverters: Error Codes - Go Power!

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)
