This coinverter unit 6SE7038-6WK86-3AF0 works in parallel with 6SE7038-6WK86-4AF0 with one common CUVC. The Alarm A017 suddenly came up and the status of the drive changed to 008.

With these faults, tried to change the IVI card and the CUVC card to a new one but the fault remained.

With the Simovert Testbox i tested all the IGBTs and all seems okay. I tried to perform a factory reset and F035 came up. what could be the cause of this?

Also after performing the test with the test box i.e passing 24V on C and D, the Inverter keeps tripping off the breaker, What could have dnl file i will give to you for further analysis..

Many thanks for your prompt and detailed support.

Please treat as very important!...cry

A017 is safe off alarm. This could be because of a missing link. Check whether your drive has this option (K80 i.e Safe off ). If yes check your drawings to find where this is connected. On the PSU2 ( power supply) board a small board will be mounted. this is the safe off option board.

The f035 is an external fault check your manual and drawings to find the reason for this fault. You must have programmed 1 i/p for external fault and the signal at that i/p terminal is not correct.

The inverter is without the k80 option. It is in the inhibit mode (r008). Tried to test with the test box IGBTs are okay. I have also changed the IPI and the CUVC card but still gives same 008 and A017.
Tried the Simulation mode but the PMU came out with E  with the op1s connected.
Any support!

Check ABO board that mounted on the |V| board, pls.
Loose,slot damage,etc.
I think that can solve your problem.

Hi
I have also had this a few times, a "safe off" alarm on a drive that does not have this function, we have actually had this a few times over the years.
We have had:
A faulty PSU board causing it.
A faulty IGD board causing it.

Thanx for your support!
Tried to change the IPI board but not still coming up. Do not have spare IGD and PSU2 on site.
Tried to power on this unit again but the main breaker keeps tripping off, What could cause this??

pls,check the fiber IGD to  IPI on the IPI side, after supply the 24 v from x9, we shuold get three fiber (uce fiber) lighting , if not O008 A017 will disply.

Hi,

Since you have the test box, try to check de UCE led, if its light than theres a problem on the IGD (on phase r, s or t) with a fault.

I´ve been facing some Warning 17 in the last months.

Talking to some Siemens Technicians, they told me that the photo transistors after 6 to 7 years of work thay are losing their properties.

Regars,

Wandrey

Photo transitor on the IVI or IGD? Please explain.

It starts as rumor

Hi 2312,

In reality, BOTH.

The IVI and the IGD both have Photo-Transistors (Detectors) and Photo-Diodes (LED's)
Over time, any electronic component WILL start to degrade, the Photo-transistors will not be as sensitive to light anymore, just as the Photo-Diodes will not emit as much light power anymore.

Don't worry about 5 - 6 years, in reality, the useable lifespan of the drive (Evironmentally dependant of course) could be anywhere upto 15 years.

For example, we are still upgrading Chassis CU1 systems to CUVC, the power part of the drives are at least 12 years old and still going strong.

The A017 alarm can simply be informing you of the K80 safety relay status (If this is fitted). If you have A017 and no K80 option, then you definately have some hardware problem in the power circuit. IVI, IGD, or IGBT (Could also be a PSU problem, but this is easy to test and disregard).

If you are starting to get optical component degradation (This includes the fibre-optic cable assembly), you will probably suffer F025, F026, and F027's.

Regards,
Graeme
