Hello all. I'm working with a Sinamics V20 drive which I am trying to get to work at 0-50Hz speed variation by using 4-20 mA. So I set the following parameters: P0756(Type of Analog input) - Parameter No=2(Unipolar current input) P0757(value x1 scaling of analog input)=4mA P0759(value x2 scaling of analog input)=20mA p1000- Analog set point = Parameter no= 2 my problem is i can not achieve exact frequency in vfd if i have gave 20mA to vfd it runs on 49.75HZ not in 50 HZ. i want to perfect 50 hz. any one know the which parameter i need to change. any one can help me to solve this issue ------------------------------------------------------------------------------------------ |
