2.4.2 Installation of additional mechanical stops on axis 1GeneralThis section details how to install additional mechanical stops on axis 1 in orderto restrict the working range of the axis.Restrictions in working rangeThe working range of axis 1 can be restricted by fitting one or two additionalmechanical stops on the casted groove at the base.The figure below shows both the minimum and maximum working range of therobot, when restricted by the additional mechanical stops. The working range canbe restricted freely within the shown scope, depending on where the mechanicalstop is installed along the casted groove.+168º-168º+64º- 64ºAABBxx0400001286Mounting position of two additional stops for maximum working area (±168º)AMounting position of two additional stops for minimum working area (±64º)BContinues on next page100 Product manual - IRB 1600/16603HAC026660-001 Revision: W© Copyright 2006-2018 ABB.
