Dear Expert,

I have a question about sinamics v20. The application is use fixed frequency settings, Forward and Reverse running. Customer need to use 2 different ramp-up time for this application. For forward run the already use Ramp-up time(P1120) and Ramp-down time(P1121) but they need to use different time for reverse running means ramp-up time 2, Can V20 do that settings? If can what paremeter required to set?

Thanks in advance..

Dear,

Thanks for your answer, I already set bico and the function of DI1 I set P0701(0)=16 and P0701(1)=2, so when bico I can use reverse running without bico I can use FF+ON but the problem is ramp-up time still same, I set P1120(0)=1.5s , P1120(1)= 15s  and P1120(2)= 15s but with bico and without bico the ramp-up only run in 1.5s. Any idea?

Dear,

Thanks a lot now I got it....
