Vito 120 alternator fail

My alternator died and changed it (new Valeo alternator) early in this year. After a while I noticed that when I am driving in the highway and when I start to accelerate at high speed red indicator light comes on the dashboard. No voltage dropping only red light comes on.

There is no problem when I push gas pedal when motor is idling.

I've changed DPF pressure sensor and Lambda sensor but no help in this fault.

Star diagnosis says Stored code 2263-001 Component G2/6 (Alternator) does not fuction properly. Faulty message or timeout

Does anybody know what can cause this kind of problem?

There is a video where you can see what happens:
