Need Help!- IPM servo drive problem

[fomaz]

Hello.

Control is 21i-M, with alfa series servo amplifiers.
Today, monday I started the machine and ... alarm. During the weekend lots of humidity on the shop, but all years the same happens.
Now that I have lots of work for the machine this happens. Really need some advice.

Error on the control is: 449 Y axis IPM error.

After digging on the net, I found that the servo amplifier displays 9. that means that the error is on the servo amplifier, related to the inteligent power module. I have disconected the servo cables and tryed everthing that I remember, and it seams that my last hope is to replace the servo amplifier. 1500€ ...

Any ideias, remarks. Anything would help.

Thanks

I will reply to myself just to leave the information for someone else in the future.

The problem was on the servo amplifier (X and Y axis). The IPM is a intelligent power module, that basically is a part made by Fuji electric.
The problem was not on the Fuji electric part but on the circuit of the servo amplifier itself. We bought a new servo amplifier and we could repair ourselves the broken one. So we have a spare servo drive.
