IP 266 Machine Data, Modes and Traversing Programs

Parameters

A traversing program (TP) is started in automatic mode. Before you can start a

traversing program, you must write it and store it on the IP 266 (see Section 5-4).

The program may contain

• positioning operations

• coordinate shifts

• corrections and

• dwells.

The IP 266 executes all programmed operations in succession. You run the pro-

gram by invoking the Start function. Program execution always begins with the

first block in the program.

The Stop function aborts the program. Any zero offsets invoked during program

execution are retained, i. e. they are not reset. Zero offsets are reset only when

the program executes in its entirety.

In automatic mode, enabled tool offsets are retained after the program

terminates or is aborted.

If a traversing program processes a rotary axis, it is preset for traversing to the

target position over the shortest possible path. Because the IP 266 itself computes

the shortest path, and thus the direction of travel, you must be aware of the

possible results of a flying change; if you have programmed a flying change, you

must know in advance whether such a change is permissible or whether it will

result in an error.

Note:

A machining program that was aborted with 'Stop' cannot be resumed at the

point of interruption.
