Dear Experts , 

I am working at a cement factory and i have a problem with a micromaster 440 , 200kW

This converter drives a induction motor 160kW installed on a dynamic separator application.

The converter is stopping  many times from alarm A0911 .

On the converter is installed an braking unit type 6SE7028-0EA87-2DA0 

and a resistor 50kW .

P1120=150

P1121=290 

Please suggest smth to eliminate this alarm .

Closed cause question posted twice.
