Conformer of cyclohexane

I want to scan potential conformers of Cyclohexane for polymorph calculations.  I was trying to use conformer module to get local and global minima as given in the tutorial.  Linear chains there is no issues, while in ring flipping cases i find a problem defining the ring closure torsions.  However, tutorial is not clear to define parameters to arrive diff conformers.
