PID Intrgral accumulates in the opposite way

[GuyM142]

I have a pid loop to turn the robot and the p and d works well. I tried to add some I but it seems that the I increases the power in the opposite way!
How can I fix it?

If you're using the built-in LabVIEW PID functions, you need to understand that the I term is a time, not a gain. The smaller the value, the more quickly the integral portion builds up. If you want very little integral accumulation, you have to specify a very long time.
