IRB1600ID fifth axis range.

Hey.

Is it possible that the robot IRB1600ID, the work area of the fifth axis, is modified to reach -135 degrees instead of -90 degrees is set originally?. Is there some mechanical interference for the fifth axis can not reach -135 degrees?. Is it harmful to exceed the fifth axis angle of -90 degrees if it were possible?.

Thank you. SmileSmileSmile
