Loader Gun rotation issue

[Devastator_cm 434]

Hi Guys, 

can someone tell me why my turret is having such weird movement? When I hit the right or left maximum range and if I keep moving my mouse in that direction further, turret suddenly comes to start point at other edge

 

Here is my config entry 

 

class loaderTurret
            {
                type="rotation";
                source="loaderTurret";
                selection="otocvelitele";
                axis="osa_velitele";
 

                sourceAddress = clamp;
                minValue = "rad -90";
                maxValue = "rad +45";
                angle0 = "rad -90";
                angle1 = "rad +45";
                minPhase = "rad -90";
                maxPhase = "rad +45";
            };

 

what is wrong here? I want only 45 degrees to right side and -90 to left as possible rotation range...
