4.2.5 TEACH IN mode

This mode can be used to create main programs and subroutines interactively.

If a program has already been selected in AUTOMATIC mode, the selection

also applies within TEACH IN.

TEACH IN only functions in the master channel of a mode group. You are

given the following two options for teach-in of a part program:

• Edit mode and

• Teach block by block.

A part program cannot be started in edit mode. There are therefore no

limitations in editing. In addition to the standard editing functions such as edit,

insert and delete, the position of the cursor can be manipulated by:

− the travel keys

− the handwheel and

− MDA operation in edit mode.

Block-by-block teach-in is a feature designed to assist the user in refining part

programs. In this mode, you can start a part program and edit it or expand it

only at the breakpoint. Advance decoding is interrupted at the breakpoint. This

ensures that a decoding error does not occur when the teach-in program is

executed later in AUTOMATIC mode, and that the teach-in contour is

reproduced correctly. You can edit the program and accept the positions at the

breakpoint.
