Owner's manual

Basic Control Operation

Chapter 2

The control provides 3 basic operation modes:

manual (MAN or MANUAL)

manual data i nput (MDI)

automatic (AUTO)

You can select a mode by using

<MODE SELECT> on the MTB panel, or

using t he

{FRONT PANEL} softkey. This is configurable by your system

installer. Both means of selection cannot be available. Details on using

the

{FRONT PANEL} softkey are given on page 2-15.

Depending on the current control status, a mode change request cannot be

honored. Operating modes may not be changed if any of these are true:

The control is in E-Stop.

The control is in the cycle-suspend state. This results when a program

is halted during the execution of a block.

The control is executing a threading- or multiple-pass turning cycle.

Important: Your system installer may have written PAL to disable the use

of the

{FRONT PANEL} softkey to change modes. If this is the case, then

changing modes can be performed by using only

<MODE SELECT> on the

MTB panel.
