Chapter 2
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
<MODE SELECT>
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
<MODE SELECT>
on the MTB panel.
