The process of restoring your controller to the factory default settings can be very simple.  The most straightforward way to do it is to create a new, empty/blank project in WinCAPSIII, and transfer it to the controller.  If done properly, this will revert the settings, parameters, and variables to a blank, default setting.

To create a blank project, please see our YouTube video or knowledge base article showing how to create a project:

Once your blank project is created, transfer it to the controller.  This will do the following:

  • The blank variable table from your new project will reset and overwrite whatever variables happen to be in the controller
  • The Arm Parameters (payload, center of gravity, software limits, etc.) will all revert to initial settings of whatever robot arm you created your project for
  • IP addresses, I/O type, internal/external power settings will all revert to the project settings.
  • Any work or tool offsets, areas of interference, arm coordinates, base coordinates, etc. will be initialized to zero

The only additional manual step you will need to take will be to clear all programs from the controller.  That can be done as follows:

Step-by-Step Guide

Step 1

From the main screen, go to Program (F1)

Step 2

Once in the Program Menu, go to Aux (F6)

Step 3

Once in Program – Auxiliary Functions, go to Delete all programs (F11)

Step 4

You will now see a dialog box asking if you want to delete all programs.  Press OK
