This is a problem where roller do not rotate , and there is a hinge as a redundancey.
Please guide how to remove this redundancey
The LocalHinge is over defining the study, causing the redundant mate.
Remove the redundant mate by deleting or suppressing it.
To have the roller "Roll" as the assembly move, one way that you could try is to use contact and gravity instead of tangent and concentric mate... (There should be better way / more efficient, but this is the first thing that pop into my mind)
You will need gravity mate in y-direction and two contact mate which are:
1. Between Bar and Roller
2. Between Roller and Bottom Plate

Thank you very much for reply , some time i face this error
any idea how to work on this error
Seem to be a convergence error.
Without looking at the file, i cant really comment.
But the first thing that i will try is checking the constraint & input, especially if you are using rotating motor in constant speed (RPM) which may cause the assembly to fail / exceed the limit. A better approach (at least in my opinion) is to use a distance motor that turn a fix distance (angle) instead of constant speed motor as it is much easier to control.
i have tried to remove all redundancies in structure , DOF is so high , please can you check file
(I am looking at new Assembly3.sldasm)
I see that you had applied various mate (eg: multiple hinge), also multiple input, which i think most of them is not needed....
Before i could actually comment, i would like to know what are you trying to achieve, or in other word, what is your design intent.
Eg: When the top plate move down, it will contact with the roller which then push the cylinder.
Without knowing whats the design intent, i cant really answer your question on whats go wrong.
actually i want to focus on these things
1) kinematics of bars
2) force required to move the top plate (up and down)
hydraulic cylinder is playing important role in this structure
This should provide some insight on how to setup the motion study...
See attached zip.
Thank you very much , going to implement it , hope make it
