Option Codes

Option codes exist on drives that have factory installed options. These options are usually the insertion of electronic boards but they may also include mechanical changes. Drives with option codes will have a “-Z” at the end of the order number (i.e. 6SE7016-1EA51-Z) followed by the appropriate codes (s) on the lines shown in the option code table (i.e. C43+).Drives that have option boards installed, but do not show the option codes on the rating plates, were shipped from the factory as basic drives and then customized by an OEM, systems integrator or the end user.
