Operating the Control

2-32

The control provides 3 basic operation modes:

Manual (MAN or MANUAL)
Manual Data Input (MDI)
Automatic (AUTO)

You can select a mode by using

on the MTB panel, or by

using the

{FRONT PANEL}

softkey. This is configurable by your system

installer. Both means of selection may not be available. Details about
using the

{FRONT PANEL}

softkey are given on page 2-11.

Depending on the current control status, a mode change request may not be
honored. Operating modes cannot be changed if any of the following 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 threading or performing a single pass turning cycle

Important: Your system installer can write PAL to disable the use of the

{FRONT PANEL}

softkey to change modes. If this is the case, then you can

change modes by using only

on the MTB panel.
