I have an assembly consisting of a shaft and wind sails. I'm using rotary motor to make the shaft rotate, and it works, but it only rotates to the left; I want it to rotate to the right, but I'm not able to. I click on reverse direction, but it stills rotates to the left. Can anyone take a look at the attached file and let me know what I'm doing wrong? Also why when I change the RPM speed (slower or faster) the speed looks the same. I'm using SW 2010.
