In 99 group which value you feed 6.2 or 2.2
1. Check field current in parameter 1.30,
2. Are you use field weeaking
If you are not using field weeaking then set field current value 6.2 in 99 group then fault rectify.

@click2electro sir I changed field bridge then during spinning speed starts decreasing from maximum speed it shows arm over current
I checked thyristor all are ok

1. Check armature current in group 1
2. If armature current value higher then motor rated value then reduce load.
3. If all are ok then need to change control card.
3. One more thing increase de-acceleration time then check.
