Full Version: PowerFlex700: Fault 918, 923, 925

Hi,
I'm working with about ten Powerflex 700, on 480V. Everything was good during the start-up until one day: one drive had a fault 925. There is nothing in the powerflex700 manual about that fault , and any other mentioned in this thread. So i'd shut down the power on the drive. In the reboot, the drive go on Fault 923, it had not reach the normal menu, ( stop in the loading). So, power down and power up = Fault 918. Again Jam before reaching the mian menu. Power reset then Fault 925. so you get the picture...

Is anybody get an idea on this?

RA Knowledgebase documents 39435 and 33902 list those fault codes, saying they are indicative of a failing main control board component or interconnect cable.

Before replacing the main control board, I'd do a thorough contamination check and examine the ribbon cables interconnecting the drive boards, as well as be sure you're running firmware 4.005 so you get the most current self-diagnostic functionality of the main control board.

If that doesn't heal the drive, replace the main control board.

The firwar are good, ribbon cale too, everything is clean. But i've talked with a guy that know a guy who have a friend that have a dog and it seem that his dog have already encounter this issue before. He told that you must turn the power down, then remove the control power ( 24 Vdc in that case) and then power up the drive. I've not try yet but what do you think of that?

Finnaly got it. the dog story is king of true. I've got to remove the input terminal block from the drive then power up. After the shut-down and re-install the block. Everything fine.
Is anyone here have heard of that trick before?

Well, no. I can't see how the 24V I/O would have anything to do with the drive detecting memory component failures unless they are conducting noise into the I/O circuitry that is propagating to the rest of the board.

Forgive me for providing advice.

dont think I do not apreciate what you do here, it's just i'm basicly french and sometime i can seem rude but i dont mean it. The thing is that the guy told that to reset that kind of fault you have to remove the control power because it's with that power that the drive keep it fault memory.

thank for the advise

and by the way i was just trying to be funny... i bet i miss my shot
