SAFETY RE-TEACH FUNCTION

Safety Re-Teach is a function that allows program path modifications in OPERATOR MODE. Limits are setup via parameters to determine the allowable position change made by the operator when the path needs to be modified for quality or safety.

Parameters are set in management security level. The manager can set limits on the maximin amount the position can be changed in X, Y & Z (mm) in one parameter and Rx, Ry & Rz (Deg) in another. There is also a parameter for the external axis (pulse counts) allowable change.

The table below lists the parameters for each controller type:

Programming Structure

Programmed position that are modified in EDITING or MANAGEMENT security level are not noted in the internal JOB contents or limited in any element. Positions modified in the OPERATOR security level are noted. Positions can only be modified within the range of the parameter for that element. The internal JOB contents is not visible on the programming pendent. After saving the job and opening in a job editor software or notepad the contents will be shown.

When modifying in OPERATOR mode and the position is outside the allowable limit the below message appears on the pendent.

Below is an example of the job contents in notepad after editing in OPERAITION mode.
