Mixed errors 08, 09, 10: are they symptoms of DA-breakdown in FP2NC? (Video)

Greetings from Sweden where (finally) spring has come.

I keep getting error 08, 09, 10 while "booting" my new to me FP2NC. These "Lageregelung" errors are from what I can gather following errors.

My situation is this:

- I boot the machine with the three-phase breaker.

- If I boot it at mode 10 up to 16, there will be no error.

- If I then push the start button (flash icon), the machinery swirls a bit, and I get error 08, 09 or 10

- Under no circumstances do the LEDs on NRP53 or NPP53 light up.

- The four LEDs on the NSV card are lit.

- If I try to swith to mode 9 or below, the machine immediately goes to error 70.

Has anyone had similar errors and traced the cause?




Some people have talked about the DA-converter HS9338 earlier.

As I understand it, this DA-converter is used to produce the "sollwerts" for the servo amplifiers. Judging from the schematic, it cycles through the outputs and the "sollwert" is buffered by a capacitor until next update.

Any input is greatly appreciated, thanks.
